You're finding the surface area of a cylinder. The formula is SA=2(pi r2)+(2 pi r)h
pi r2 is the surface area of a circle. You need two of these, one for the top and one for the bottom of the can. Thus, 2(pi r2).
2(pi 42)= 2(16pi)=32pi
Next, you need the surface area of the body of the can. First, you need the perimeter of the can. perimeter=2 pi r. then you multiply that by the height of the can. SA of the body of the can=(2 pi r)h
(2 pi 4)14=(8pi)14=112pi
Finally, you add the two answers together to get the total surface area of the can.
32pi+112pi=144pi=351.858 cm2

What is the body structure of roundworms?
Roundworms have long, cylindrical bodies that taper at both ends. They have a complete digestive system with a mouth and an anus, and their bodies are covered in a protective cuticle. Roundworms also have a fluid-filled body cavity called a pseudocoelom.
Which planet was studied by the Mariner 10 probe and has a crater-covered surface?
The Mariner 10 probe studied the planet Mercury, which has a heavily cratered surface due to impacts from asteroids and meteors. It is the smallest and closest planet to the Sun in our solar system.
What are the characteristics of axonS?
Axons are long, thin, and cylindrical extensions of nerve cells that transmit electrical impulses away from the cell body to other neurons, muscles, or glands. They are covered by a protective myelin sheath, which helps to speed up the transmission of nerve signals. Axons can vary in length from a few millimeters to over a meter depending on the neuron's location in the body.
What is The planet known for being covered in cliffs and craters and having a weak magnetic field is?
The planet known for being covered in cliffs and craters and having a weak magnetic field is Mercury. It is the closest planet to the Sun and has a surface marked by extensive impact craters due to its lack of a significant atmosphere. Mercury's weak magnetic field is a result of its small size and slow rotation, which limits its ability to generate a strong dynamo effect.
Is The lower epidermis covered with cuticle?
No, the upper epidermis is covered by a cuticle.
A square centimeter is the area covered by a square whose sides are 1 meter long?
false
What part of the surface of the Earth covered by ocean is closest to the shore?

When Pompeii was covered in ash in 79 AD what was the closest to Pompeii?
This question makes no sense.
What is area covered by a circular rug whose radius is 160 centimeters?
1.62 pi m2
What is a word that starts with a that mean covered with water?
The closest thing I can think of is aquatic, hope that helps.
Has a long cylindrical body pseudocoelom and gets its shape from its epidermis and cuticle?
This description matches the anatomy of a roundworm, also known as a nematode. Nematodes are unsegmented worms with a long, cylindrical body that is covered by an epidermis and cuticle. They have a fluid-filled body cavity called a pseudocoelom.
What is a cc in a vehicle?
It's the volume(cc= cubic centimeters) covered by the piston of the cylinder in your car's engine. The more the better.
What is a coaxiale?
Coaxial cable is an electrical cable with one wire in the center surrounded by a layer of insulation which is then surrounded by an outer braided cylindrical conductor and finally covered with another insulating layer.
Is a square centimeter the area covered by a square whose sides are 1 meter long?
Nope... A square centimetre measures 10 millimetres on each side.
How many tiles of size 30 centimeters by 20 centimeters will be placed in a room measuring 500 centimeters by 400 centimeters?
Area to be covered = 500*400 cm2 = 200000 cm2 Area of tile = 30*20 cm2 = 600 cm2 So number of tile required = 200000/600 = 333.3.. that is, 334 tiles.
What is a coaxial cable?
Coaxial cable is an electrical cable with one wire in the center surrounded by a layer of insulation which is then surrounded by an outer braided cylindrical conductor and finally covered with another insulating layer.
Is perimeter cm squared in math?
No. Square centimeters refer to an area covered, while just plain centimeters refer to a length (like a line). The perimeter of a shape is linear, so it's referred to just in cm.
