Answer:
Given the statement: Crater Lake in Oregon in shaped like a circle with a diameter of about 5.5 miles.
Area of circle is given by:
[tex]A = \pi \frac{d^2}{4}[/tex]
where
A represents the area of a circle
d represents the diameter of a circle.
then;
It is given that Surface of Crater lake is shaped like a circle.
Substitute the given values, we have;
Area of a circle = [tex]\pi \frac{(5.5)^2}{4}[/tex]
= [tex]3.14 \times \frac{30.25}{4} =3.14 \times 7.5625 = 23.74625[/tex] square miles
therefore, the area of a surface of a crater lake is, 23.74625 square miles.
