Question

(Will give Brainliest) These are composite figures. find the area of the figure and round your answer to one decimal place if necessary.

Answer 1

Answer:

468.5 in

(??? gonna be honest I'm not sure its right but gave it a shot so apologies if I gave u a wrong answer)

Step-by-step explanation:

(this is how I did it, like I said, not sure its right)

Dotted line:

we need to find the length of the dotted line in order to be able to calculate the area of the rectangle

radius = 8 in

diameter (dotted line)

               = 8 x 2

               = 16 in  

(radius is half the diameter so now you know the length of the dotted line is 16 in - this answer is for the rectangle)

Area of the rectangle

A = L x W

using the 16 we found to calculate the area of the rectangle

                A = 23 x 16

                A = 368 in

Area of semi-circle:

Now to calculate the area of the semi-circle

A = π r² ÷ 2

             A = π 8² ÷ 2

                 = 100.48

Adding the area of the rectangle and semi-circle together:

               = 100.48 + 368

               = 468.48

        1dp = 468.5

tried to explain it as well as possible

sorry if its wrong
