Question

A circle has a circumference of 50.24 units. What is the radius of the circle?

Answer 1

Answer:

r=8

Step-by-step explanation:

c=2$\pi$r

50.24=2$\pi$r

Divide by 2 on both sides

25.12=$\pi$r

Divide by pi/3.14 on both sides

r=8

Hope this helps!

Answer 2

Answer:

r = 8 units

Step-by-step explanation:

$C = 2\pi \: r \\ 50.24 = 2 \times 3.14 \times r \\ 50.24 = 6.28\times r \\ r = \frac{50.24}{6.28} \\ r = 8 \: units$

Hence, radius of the circle is 8 units
