Question

estimate the area of the circle shown belowA) 75 cm^2B) 25 cm^2C) 30 cm^2D) 58 cm^2

Answer 1

Given:

Radius of the circle is 5.2 cm.

The area of the circle is calculated as,

$\begin{gathered} A=\pi\times r^2 \\ \text{Here, r=5.2} \\ A=\pi\times(5.2)^2 \\ A=27.04\pi \\ A=27.04\times3.14\ldots\ldots\ldots\ldots\text{ Since }\pi=3.14 \\ A=84.9cm^2 \end{gathered}$

Answer: Area of the given circle is 84.9 cm².
