Answer:
The answer is 12.25 cm
Explanation:
Given;
- Circumference (C) = 77 cm
- π = 22/7
To Find;
Formula;
2πr = C
To make subject r divide both side by 2π we get,
2πr/2π = C/2π
r = C/2π
r = 77 ÷ 2 × 22/7 cm
r = 77 × 7 ÷ 2 × 22 cm
r = 539 ÷ 44 cm
r = 12.25 cm
Thus, The radius (r) of the circle is 12.25 cm
