Below is the net of a cylinder. What is the area of the top circle?

r=4cm h= 8cm

1 answer

The formula for the area of a circle is A=πr^2, where r is the radius of the circle. Since the radius of the top circle is given as 4cm, we can use this formula to find its area:

A = π(4cm)^2
A = 16π cm^2

Therefore, the area of the top circle is 16π square centimeters.
