The area of a circle with a radius of 7 cm is approximately 158.36 square centimeters.

The area of a circle with a radius of 7 cm is approximately 158.36 square centimeters.

True or false??

False
A=πr^
the answer is about 153.86 square centimeters

The equation for the area A of a circle with radius r is:
A = pi * r^2

So here, the radius is 7 cm, so all we have to do is substitute that in for r and we get
A = 3.14 * (7 cm)^2 = 3.14 * 49 cm^2 = 153.86 cm^2
So the answer is false. The area is approximately 153.86 square centimeters, not 158.36.

No, it's actually 153.938 square centimetres:

Pi x R x R = the area.

R x R = 49
49 x Pi = 153.938

False.. try solving it in a calculator using this formula..A=pi x r^2
