Answer:
12.25
Step-by-step explanation:
77 divided by 22/7 = 24.5 That is the diameter
12.25 is the radius
Answer:
The answer is 12.25 cm
Step-by-step explanation:
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
