Question

The radius of the circle shown below is 3 inches. What is the area of this circle, in square inches? 3 in A 37 B 971 1271 3671

Answer 1

The expression for the area of circle with radius 'r' is :

`\text{ Area of Circle=}\Pi(radius)^2,\text{ where }\Pi=3.14`

In the given question we have radius = 3 inches

Substitute the value and simplify :

`\begin{gathered} \text{ Area of Circle=}\Pi(radius)^2 \\ \text{Area of Circle=}\Pi*3^2 \\ \text{Area of Circle=}\Pi*9 \\ \text{Area of Circle=9}\Pi inches^2 \end{gathered}`

Answer : B) Area of circle = 9 pie
