Question

Can anyone help me out

Answer 1

Answer:

62

Step-by-step explanation:

length of rectangle = 2* diameter = 24

width  = diameter = 12

area = 24*12 - 2 * pi * 6^2 = 61.8

Answer 2

Your answer would be the second option, 62.

To answer this we need to find the area of the 2 circles, and then subtract this from the area of the rectangle to find the shaded area.

The equation for the area of a circle is πr², so for one circle this would be π × 6² = 36π. Since we're taking π = 3.14, this comes out as 113.04 as the area for once circle, which means the area for both circles would be 113.04 × 2 = 226.08.

To find the area of the rectangle, we need to notice that the height of the rectangle is the diameter of one circle, and the width is 2 multiplied by the diameter of the circle, because there are 2 diameters right next to each other. The diameter of one circle is 6 × 2 = 12, so this is the height, which means the width of the rectangle is 12 × 2 = 24. This means the area of the rectangle is 24 × 12 = 288.

Now the last step is to do 288 - 226.08 = 61.9 = 62.

I hope this helps!
