Question

Help on finding area!

Answer 1

Answer:

b is your answer, 366.7

Step-by-step explanation:

You can split this into 2 shapes to find the area, a rectangle and a circle (split into 2 parts on either end of the rectangle). The area of the rectangle inside is the easiest part, so let's start there.

Area of a rectangle = length x width = 18 x 13 = 234. We'll come back to this number in the last step.

The area of a circle = (pi)(r)^2 = (pi) (radius)(radius).

The radius = 1/2 of the diameter, and the diameter is 13, so the radius = 6.5

We'll use 3.14 for pi, since the answers are in decimals, not fractions.

area = (3.14)(6.5)(6.5) = 132.665

------------------------------

Now add the area of the circle to the area of the rectangle.

234 + 132.665 = 366.665 , rounded to 366.7  on your question.
