Question

Find the diameter and radius of a circle with a circumference of 65.98 Please help ​

Answer 1

21 and 10.5 respectively

Explanation:

Remember circumference of a circle is given as;

C= 2×π×r; r is raduis

r = C / 2×π

=65.98/(2×3.142)= 10.50

D= 2× r = 2× 10.50= 21.0( D represent diameter)

Note π = 3.142 a known constant
