Question

If the circumference of the circle is 37.68 units, what is the area? (Use 3.14 for pi .)

Answer 1

Answer:

Area of the circle = $113.04\;units^2$

Step-by-step explanation:

Circumference = $37.68\;units$

Circumference of the circle = $2\times \pi \times r$

As,

    $\pi =\dfrac{22}{7}=3.14$

                        $37.68=2\times \pi \times r\\\\37.68=2\times 3.14 \times r\\\\37.68=6.28\times r\\\\r=\dfrac{37.68}{6.28} \\\\r=6\;units$

Area of a circle = $\pi \times r^2$

                       $=3.14\times (6\times 6)\\\\=3.14\times 36\\\\=113.04\;units^2$

Answer 2

Answer:

113.04 units²

Step-by-step explanation:

A = πr2 = π(d2)2 A = C24π π = 3.1415 A = area C = circumference or perimeter r = radius, d = diameter
