Answer:

87.92 inches cubed or 87.92 in.^3

Step-by-step explanation:

The base of a cylinder is a circle, so we need to calculate the area of the circle first. The equation for the area of a circle is:

area (a) = pi * r^2 =3.14*2*2 =12.56sq.inches

again,

volume of cylinder = area of the base * the height

= 12.56 * 7

= 87.92 inches cubed or 87.92 in.^3

Answer:

130 yd^2

Step-by-step explanation:

First we find the area of the triangle

A = 1/2 b h  where b is 10 and h= 6.25

A = 1/2 (10) * 6.25

   = 31.25 yd^2

Then we find the area of rectangle A

A = l*w  where l is 10 and w = (7.5-2.5) = 5

A = 10 * 5

   = 50 yd^2

Then we find the area of rectangle B

A = l*w  where l is 6.5 and w = 7.5

A = 6.5 * 7.5

   = 48.75 yd^2

The total area is found by adding them together

A triangle + rectangle A  + rectangle B

31.25+50 + 48.75

130 yd^2
