Question

Find the area

Answer 1

Area of rectangle A = L * W
Area of a circle A = pi r^2

first find the area of the rectangle.

Then find the area of the circle, they give you the diameter
2 half circles are = 1 circle

subtract the area of the circle from the area of the rectangle

Answer 2

Notice how if you put the two semicircles together, they form 1 single circle with a diameter of 14. To get the area of the remaining area, we must first find the area of the rectangle, given by: \(\bf Area=Length \times Width \) Then you need to subtract the area of the circle from the area of the rectangle, and the area of a circle is given by \(\bf Area=\pi r^2,where \ r=\frac{1}{2}d \). r is the radius and d is the diameter.

And that will give you the remaining area.

Answer 5

what is the area of the rectangle 14*28

Answer 6

392

Answer 7

Nope.

Answer 8

what is the area of the circle 3.14(7^2)

Answer 9

153.86

Answer 10

so is the total area 238.14cm2 ?

Answer 11

now subtract the circle from the rectangle

Answer 12

392 - 153.86

Answer 13

makes sense?

Answer 14

Look:\[\bf Area \ of \ Rectangle=14 \times 28\]\[\bf Area \ of \ Circle=\pi r^2=\pi(7)^2\]After getting both areas, subtract circle's area from the rectangle's area.
