Question

A circle has a radius of 7 inches. What is the area of the circle? Use 3.14 for p.

(Area of a circle = pr2)

Answer 1

Here, we are given with a circle whose radius = 7 inches, and we are asked to find the area of the circle. Taking value of π = 3.14

We know,

• Area of the circle = πr²

Here,

• π = pi (An irrational number used for curves)
• r = radius of the circle

So, let's find the area,

➝ Area of the circle = πr²

➝ Area of the circle = 3.14 × 7²

➝ Area of the circle = 3.14 × 49

➝ Area of the circle = 153.86 inch²

Hence, Area of the circle:

`\huge{ \boxed{ \bf{153.86 \: {inch}^(2) }}}`

And we are done !!

Answer 2

The answer is

153.86 sq. inches

Explanation:

Area of a circle is given by

A = πr²

where r is the radius of the circle

From the question

r = 7 inches

So the area of the circle is

A = 3.14(7)²

= 3.14 × 49

We have the final answer as

153.86 sq. inches
