Question

Find the circumference and the area of the circle whose radius is 8.4cm

Answer 1

Hello ☺️❤️☺️

_______________________

Radius = 8.4 cm

Circumference = 2 π r

⇒ 2 × 22 / 7 × 8.4

⇒ 369.6 / 7

⇒ 52.8 cm

Area = π r²

⇒ 22 / 7 × 8.4 × 8.4

⇒ 1552.32 / 7

⇒ 221.76 cm²

GIVEN ▶

Radius of circle ▶8.4cm

circumference ?

so,

circumference of circle ▶2πr

=2×22/7×8.4

=52.8 cm

And,

Area of circle ▶πr^2

=22/7×8.4×8.4

= 221.76 cm^2

THANKS ✌☺
