How do you find the radius of a sphere when you know the area

1 answer:

8 0

Since the area formula is pi times radius to the second power, then just plug in the things you know. for ex: The area is 314, then work backwards and divide 314 by pi which equals 100 then unsquare it which is 10 because 10*10=100. So the radius is 10

IrinaK [193]

Answer:

4w+8 feet

Step-by-step explanation:

The perimeter of a rectangle is the sum of the lengths of its sides. Since opposite sides are identical in length, it can be computed as double the sum of adjacent side lengths. Here, the lengths are in feet.

P = 2(L+W)

P = 2((w+4) +w)

P = 4w +8

The perimeter of the patio is 4w+8 feet.
