Chapter 11.8, Problem 1CYU

To determine

To compute the area of the circle.

Answer to Problem 1CYU

  $154$ squaremeters.

Explanation of Solution

Given information:

Radius ‘r’$=7$ meters.

Formula used:

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

Calculation:

  $A=\pi \times r^2$

Formula for area of the circle.

  $=\frac{22}{7}\times 7\times 7$

Taken ‘pi’ as $\frac{22}{7}$ .

  $=22\times 7$

Multiplying the same.

  $=154$ square meters.
