Chapter 11, Problem 37SGR

To determine

To calculate the area of circle.

Answer to Problem 37SGR

  $201.14c{m}^2$

Explanation of Solution

Given Information: Radius = 8 cm.

Formula Used:Area of circle = $\pi \times r^2$ , $\pi =\frac{22}{7}$

Calculation:

Radius = r.

Area of circle = $\pi \times r^2$

Now, radius is of 8 cm.

Area of circle = $\pi \times 8^2$

Now, $\pi =\frac{22}{7}$

Area of circle = $\frac{22}{7}\times 8\times 8c{m}^2$

Area of circle = $201.14c{m}^2$
