Question

find the circumference and area of this figure. c = ? units a = units² use π = 3.14 round your answer to the nearest hundredth

Explanation:

Step1: Find the radius

The two points on the circle are at \((1,7)\) and \((3,7)\). The distance between them (diameter) is \(3 - 1=2\) units. So radius \(r=\frac{2}{2}=1\) unit.

Step2: Calculate the circumference

The formula for circumference \(C = 2\pi r\). Substitute \(r = 1\) and \(\pi=3.14\).
\(C=2\times3.14\times1=6.28\)

Step3: Calculate the area

The formula for area \(A=\pi r^{2}\). Substitute \(r = 1\) and \(\pi = 3.14\).
\(A=3.14\times1^{2}=3.14\)

Answer:

\(C = 6.28\) units, \(A=3.14\) units²
