Question

A circle has a radius of 5 centimeters. What is its area?

Answer 1

the area is 78.5 cm because the formula is A=3.14r^2 or area=3.14•5^2

Answer 2

`\bf \huge 78.5 \: c.m.`

Explanation:

Given that :

• A circle has a radius of 5 centimeters.

to find :

• What is its area?

formulas used :

• A = πr²

where,

• A = area
• π = 22/7
• r = radius

explanation :

finding the area of circle

⟼ A = πr²

⟼ A = 22/7 × 5²

⟼ A = 22/7 × 5 × 5

⟼ A = 3•14 × 5 × 5

⟼ A = 3•14 × 25

⟼ A = 78•5

∴ the area of circle is 78•5 centimeters
