Here's what you do... take a graph paper.. the 1mm x 1mm graduated. trace the leaf on the graph paper. remove the leaf. then count the whole squares occupied by the leaf. write down the number. count the half 3/4th filled squares and write the number down. count the number of half filled squares and divide the number by two and write it down. leave out 1/4th filled squares. add the numbers you have written down. the number you get is the surface area of one side of leaf. doubling it will give you the surface area of the entire leaf in sq cm

What is the instrument used in a sumberine to see above the surface of water?
A periscope is the instrument used in a submarine to see above the surface of water. It works by using mirrors to reflect light down into the submarine while allowing for observation of the surface without exposing the submarine itself.
What is wattage of an instrument if you only know it is 220V50Hz?
To determine the wattage of an instrument with a voltage of 220V and a frequency of 50Hz, you need to know the current it draws (in amperes). Wattage can be calculated using the formula: Wattage (W) = Voltage (V) × Current (A). Without the current value, the wattage cannot be determined.
What is the instrument that measures changes in air pressure without using a liquid?
An aneroid barometer is an instrument that measures changes in air pressure without using a liquid. It uses a flexible metal box called an aneroid cell that expands and contracts with changes in pressure, which is then translated into a measurement on a dial.
Can you play wind instruments without a tongue?
Yes, some wind instruments can be played without using your tongue by using alternative techniques such as breath control, embouchure adjustments, and manipulating air flow within the instrument. However, the tongue is commonly used to articulate notes and create different sounds on wind instruments.
What Instrument measures A wind vane?
An anemometer is the instrument that measures wind direction using a wind vane.

How can one determine latitude and longitude without using GPS technology?
Latitude and longitude can be determined without using GPS technology by using tools such as a sextant, astrolabe, or a compass. By measuring the angle of the sun or stars above the horizon, sailors and navigators can calculate their position on the Earth's surface. Additionally, landmarks, maps, and celestial navigation techniques can also be used to determine latitude and longitude.

What direction can be measured using what instrument?
Direction can be measured using a compass, which points towards the Earth's magnetic poles. This instrument uses the Earth's magnetic field to determine north, south, east, and west directions.
What should not be done when sanitizing an instrument?
When sanitizing an instrument, avoid using abrasive materials or harsh chemicals that can damage the instrument's surface or functionality. Do not rush the process; ensure that the sanitation procedure is followed thoroughly for effective disinfection. Additionally, never skip rinsing or drying steps, as residue can compromise cleanliness. Lastly, avoid using the same sanitizing solution for multiple instruments without proper disposal or refreshing.
It is possible to draw a perfect circle without any instrument?
yes it is possible by using a coin
Can an aircraft land at an airport using an instrument or precision approach without approach lights?
yes
How do you determine the volume of sugar without using water displacement?
it will dissolve
How can screw hooks be installed without using a drill?
Screw hooks can be installed without using a drill by using a screwdriver and manually twisting them into the desired surface.
An electric charge can be detected by an instrument called?
An electric charge can be detected by an instrument called an electroscope. It works by using the principles of electrostatics to determine the presence and type of charge on an object.
How can one determine temperature without using a thermometer?
One can determine temperature without using a thermometer by observing physical changes in materials, such as the melting point of ice or the boiling point of water, or by using the sense of touch to feel the warmth or coolness of an object.
