Question

what is the circumference of 25π and what it radius​

Answer 1

$circumference = 25\pi$

radius =?

circumference =2 × pi × r

25 ×pi =2×pi ×r

r=25/2

r=12.5

plz follow me

Answer 2

Step-by-step explanation:

Given,

Area of circle = 25π.

πr² = 25π

⇒ r² = 25

⇒ r = 5

Then,

Circumference of circle = 2πr

= 2 * 22/7 * 5

= 31.42 units.

Therefore,

Circumference = 31.42 units

Radius = 5 cm

Hope it helps!
