To solve this, we are going to use the surface are of a sphere formula:

where

is the surface area of the sphere

is the radius of the sphere
We know for our problem that

and

, so lets replace those vales in our formula:



Now, we just need to solve our equation for

:





or

Since the radius of a sphere cannot be a negative number,

.
We can conclude that the radius of a sphere with surface area <span>2,122.64 </span>

is
13 in.
Answer:
B
Step-by-step explanation:
let f(x) = y and rearrange making x the subject
y =
( multiply both sides by 7 to clear the fraction )
7y = x + 2 ( subtract 2 from both sides )
7y - 2 = x
Change y back into terms of x with x the inverse function, that is
p(x) = 7x - 2
Answer:
32$ < x < 48$
Step-by-step explanation:
Erika estimates that her destination is between 200 and 300 miles away.
When we divide 200 with 25 miles we get 200/25 = 8 gallons
When we divide 300 with 25 miles we get 300/25 = 12 gallons
When we multiply 8 · 4 = 32$ we get amount of money for destination
200 miles x = 32$
When we multiply 12 · 4 = 48$ we get amount of money for destination
300 miles x = 32$
Since that the estimate destination is between 200 miles and 300 miles
then the best estimate for the amount of money is between
32$ < x < 48$
God with you!!!
