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

r = 6.2ft, C = 38.96ft

Step-by-step explanation:

Given the value for the diameter d = 12.4ft

To get the radius;

`\begin{gathered} \text{radius =}(diamater)/(2) \\ r=(d)/(2) \\ r=(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
