Question

The area of a circle is 16 pi what is the diameter of circle

Answer 1

Step-by-step explanation:

As we have given the area of circle is 16π

we know that,

Area of circle = π r²

therefor,

⟹ 16 π = πr²

⟹ 16 = r²

⟹ r² = 16

⟹ r = √16

⟹ r = 4

Diameter of circle = 2 x radius

= 2 x 4

= 8

therefor, the diameter of circle is

8 units

Answer 2

Given,

Area of the circle = 16π

We know that,

Area of Circle = πr²

According to the problem,

πr² = 16π

r² = 16

r = √16

r = 4cm

Diameter of Circle = 2 × radius

= 2 × 4

= 8cm

Therefore, the diameter of Circle is 8cm.
