Question

find the area and te circumference of the circle whose radius is 12 ft​

Answer 1

Step-by-step explanation:

area formula = πr^2

3.14*12*12 = 452.16

Circumference formula = 2πr

2*3.14*12=75.36

Answer 2

Step-by-step explanation:

Analyzing the question,

Given:

• Radius = 12 feet

To find:

• Area of circle = ?
• Circumference of circle = ?

Solution:

First, let's find out the area of the circle

We know that,

Area of circle = πr²

→ Area of circle = 22/7 × 12 × 12

→ Area of circle = 22/7 × 144

→ Area of circle = 452.57 ft²

Now, let's find out the circumference of the circle.

Circumference of circle = 2πr

⇒ Circumference of circle = 2 × 22/7 × 12

⇒ Circumference of circle = 24 × 22/7

⇒ Circumference of circle = 75.43 ft

Hence,

• Area of circle = 452.57 ft²
• Circumference of circle = 75.43 ft
