Question

The radius, diameter, or circumference of a circle is given. Find the missing measures.Round to the nearest hundredth if necessary.d = 12.4 ft, r= ?, C= ?O r = 6.2 ft. C = 38.96 ftO r = 24.8 ft. C = 38.96 ftor= 24.8 ft. C = 19.48 ftO r = 6.2 ft. C = 19.48 ft

Answer 1

Answer:

r = 6.2ft, C = 38.96ft

Explanation:

Given the value for the diameter d = 12.4ft

To get the radius;

$\begin{gathered} \text{radius =}\frac{diamater}{2} \\ r=\frac{d}{2} \\ r=\frac{12.4}{2} \\ r=6.2ft \end{gathered}$

Get the circumference;

$\begin{gathered} C=\pi d \\ C=3.14\cdot12.4 \\ C=38.96ft \end{gathered}$

Hence the radius is 6.2ft and the circumference is 38.96ft
