nlexa [21]

Answer:

SA=62.8\ ft^2

Step-by-step explanation:

we know that

The surface area of a cylinder is equal to

SA=2\pi r^{2}+2\pi rh

we have

h=3\ ft

r=4/2=2\ ft ----> the radius is half the diameter

assume

\pi =3.14

substitute

SA=2(3.14)(2)^{2}+2(3.14)(2)(3)

SA=62.8\ ft^2

The length of a rectangle is 7 inches more than its width. If the perimeter of the rectangle is 66 inches, find the dimensions.
Igoryamba

Answer:

13 by 20 inches

Step-by-step explanation:

Represent the quantities as follows:

P = 2W + 2L

L = W + 7

Then P = 2W + 2(W + 7), or P = 4W + 14

and this formula has the value 66 inches.

Thus, P = 66 inches = 4W + 14 inches, or

                52 inches = 4W

Dividing both sides by 4, we get W = 13 inches.

The width is 13 inches and the length is (13 + 7) inches, or 20 inches.
