Answer:
The radius of the circle is 14 cm and its circum. Is 88cm
Step-by-step explanation:
Given ::- area of circle is 616 cm²
To find ::- radius and circumference
Solution::-
A(circle) = πr²
616 = 22/7 × r²
616 × 7 /22 = r²
28 × 7 = r²
196 = r²
r = 14 cm (taking sq. rt. on both sides)
Therefore the radius of the circle is 14cm
Now,
Circumference of circle = 2πr
= 2 × 22/7 × 14
= 2× 22 × 2
= 4 × 22
= 88 cm
Therefore the circumference of the circle is 88 cm
