Question

A circle has a circumference of 150 meters. What is the measure of its radius? Round

Answer 1

Answer:

23.9

Step-by-step explanation:

circumference = Diameter · Pie

150 = X · pie

divide both sides by pie(use the accrual symbol on a calc) and you get 47.7 as the diameter then divide 47.7 by 2 and you get 23.9 as you radius

Answer 2

Answer:

$2\pi \times \: r = 150 \\ 6.2831r = 150 \\ \frac{6.2831r}{6.2831} = \frac{150}{6.2831} \\ r = 23.87cm$
