Below is the net of a cylinder. What is the area of the top circle?
r=4cm h= 8cm
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.
To find the area of the top circle of the cylinder, we need to know the formula for the area of a circle. The formula for the area of a circle is A = πr^2, where A represents the area and r represents the radius of the circle.
In this case, the radius of the circle is given as 4 cm. Therefore, using the formula, we can calculate the area of the top circle as follows:
A = π * r^2
= π * (4 cm)^2
= π * 16 cm^2
≈ 50.27 cm^2
Therefore, the area of the top circle of the given cylinder is approximately 50.27 square centimeters.
