If the area of a circle is 58 square feet, find the circumference.
A. 26.99 ft.
B. 4.25 ft.
C. 42.5 ft.
D. 22.35 ft

If the area of a circle is 58 square feet, the circumference is 26.99 ft. Solution: Area = pi *r^2 , 58 = 3.14 *r^2 , r^2 =58/3.14 =18.47 , r = 4.29 , Circumference =2 *pi *r = 2 *3.14 *4.29 = 26.99 ft.

The length of a rectangle is 12 in. and the perimeter is 56 in. The width of the rectangle is 16 in.

SOLUTION:

Length of two of the sides = 12 x 2 = 24 in.

Total width of the other two sides = 56 - 24 = 32 in.

Width of one side = 32/2 = 16 in.

SOLUTION:

Length of two of the sides = 12 x 2 = 24 in.

Total width of the other two sides = 56 - 24 = 32 in.

Width of one side = 32/2 = 16 in.

The length of the pipe is 17 feet. Solution: Joel is laying pipe for a sprinkler system before he plants his lawn. The lawn is a rectangle, 15 feet long and 8 feet wide. He needs to lay a piece of pipe that will run along the diagonal of the lawn. It will divide the area of the lawn into two right triangles. Using Pythagoras' theorem, (15 x 15) + (8 x 8) = the square on the hypotenuse (the diagonal). 225 + 64 = 289. The square root of 289 is 17. (17 x 17 = 289).
