Find the area of a circle with a circumference of 34.6 feet

andrew11 [14]

Answer:

Area of the circle = $95.33feet^2$

Step-by-step explanation:

Circumference of the circle=34.6 feet

Circumference of a circle= $2\pi r$

$34.6=2\pi r\\\\$

As, $\pi =\frac{22}{7}=3.14$

$34.6=2*3.14*r\\\\34.6=6.28*r\\\\34.6/6.28=r\\\\r=5.51feet$

Area of the circle= $\pi r^2$

$=3.14*5.51*5.51\\\\=3.14*30.36\\\\=95.33feet^2$

The area of the circle is $95.33feet^2$
