Question

Find area of area circle whose circumference is 132cm

Answer 1

The area of the circle=1386cm*

Answer 2

Given:

• Circumference of the circle is 132 cm.

Need to find:

• The area of the circle = ?

Solution:

Circumference of circle = 132 cm

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀2πr = 132 cm

⠀⠀⠀⠀⠀⠀ ⠀2 × 22/7 × r = 132 cm

⠀⠀⠀⠀⠀ ⠀ 44/7 × r = 132 cm

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀r = 132 × 7 / 44

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀r = 21 cm

Area of circle = πr²

➜ Area of circle = 22/7 × 21 × 21

➜ Area of circle = 22 × 3 ×21

➜ Area of circle = 1386 cm²

Therefore,

The area of the circle is 1386 cm².
