Question

Find the area of the circle with radius =3 ¼ yd.help

Answer 1

Given in the question:

a.) A circle with a radius of 3 ¼ yds.

Let's recall the formula in getting the area of a circle:

$\text{Area = }\pi r^2$

Let's substitute the given radius to find the area. We get,

$\text{Area = }\pi r^2$$\text{Area = }\pi(3\frac{1}{4})^2\text{ = }\pi(\frac{13}{4})^2$$\text{ = }\pi(\frac{169}{16})$$\text{ = }\frac{169}{16}\pi\text{ yds. }\approx\text{ 33.18 yds.}$

Therefore, the area of the circle is 33.18 yds.
