when radius = 4 cm
area = 3.14*4*4=50.24 cm2
That is a good approximation. The actual answer is 3.937 inches. One centimeter is equal to .3937007878 inches, usually rounded to .394. To convert centimeters into inches, multiple the centimeters by .393700787.
7.62 cm = 3 inches = 1/4 foot
40 m is larger than 400 cm.40 m is equal to 4000 cm which is greater than 400 cm. 400 cm is only equal to 4 m.
Answer not possible to get area from one length measurement unless given the shape of this length. For example if the shape is a square of perimeter 27 cm. then the side length is 27/4 and the area is (27/4) x (27/4) square cm.
One hand is equal to 4 inches. In each inch there are 2.54 cm. So, 122 cm is equal to 48.0 inches. This equals 12 hands.
4 cm radius = Area of 50.26548 sq. cm.
A circle with a radius of 4 cm has an area of 50.27 square cm.
A circle with a radius of 4 cm has an area of 50.27 square cm.
A circle with a radius of 4 cm has an area of 50.27 square cm.
Area of a circle = pi x (radius)2So, if the radius is 4 cm, the area is pi x 42= 50.265 cm2
A=Pi(r)2 - A circle with a radius of 4 cm has an area of 50.27 square cm
The probability as a fraction that a point chosen at random within a circle of radius 10 cm will be inside a concentric circle of radius 4 cm is the ratio of the area of the smaller circle (4 cm radius) to the area of the larger circle (10 cm radius). Therefore, the probability is (4^2)/(10^2) = 16/100 = 4/25.
Area = pi*radius-squared. Therefore, area = pi*4*4 sq cm = 50.27 sq cm.
The area of a circle = pi x radius squared where pi = 3.1416 therefore area = 3.1416 x 4 x 4 = 50.26 square cm
Area = pi*42 = 50.26548246 or about 50 square cm
The area of a sector in a circle if the radius is 4 cm and the arc has degree 120 is: 16.76 cm2
This indicates a radius of 4 cm, in which case the area of the circle is: 50.27 square cm
