Question

Find the radii of the circle whose area is : (Take π = 3.14)
706.5cm².​

Answer 1

Answer:

Given,

Area of circle = 706.5cm²

We know, Area of circle = π × r² [where r = radii of the circle]

Therefore, Radii of the circle =√(706.5/3.14)

= √225 = 15 cm

Answer 2

Answer:

50.24cm

Step-by-step explanation:

As we know that,

Area of circle =πr²

Area of circle =200.96cm² (Given)

∴πr² =200.96

⇒r² = 200.96/3.14

⇒r = √64

=8cm

Therefore,

Circumference of circle =2πr

=2×3.14×8

=50.24cm
