Question

Find the area of a circle whose radius is 7cm(take π=22/7)

Answer 1

Given :

• Radius of circle = 7 cm

To Find :

• Area of circle

Solution :

Area of circle = π r²

→ 22/7 × 7 × 7

→ 22 × 7

→ 154 cm²

Area of circle is 154 cm²

Extra info :

Circumference of circle = 2 π r

Area of sector = π r² × Ø/360°

Answer 2

Answer:

Radius of the given circle = 7cm

Area of a circle= πr^2

= 22/7×7cm×7cm

= (22×7) cm square

= 154 cm^2
