Question

find the radius of the circle whose circuference is: (a) 44cm​

Answer 1

Answer:

use formula pier^2(pie=22/7,r=radius,and then the ans u get just square it :)

Answer 2

Answer:

7 is the Radius.

Step-by-step explanation:

Circumference= perimeter

perimeter of a circle = 2$\pi$r

and we have perimeter to be 44 cm

we need to find the radius.

Now, 44 = 2$\pi$r

44 = 2 × 22/7 × r

44/2 = 22/7

22×7/22 = r

22 and 22 gets cancelled.

so, we get 7 to be our radius.

we conclude that

∴ Radius = 7 cm
