Answer:
C
Step-by-step explanation:
The volume (V) of a sphere is calculated using the formula
V = 
πr³
If the radius is doubled, that is r = 2r , then
V = π (2r )³
(2r)³ = 8r³, thus the volume is multiplied by 8
Answer:
5 sq. ft.
Step-by-step explanation:
To find the area of a rectangle, use this formula: A = lw.
Because you know two side lengths of the window, you can just plug in the numbers to the formula.
But not yet! You need to convert the given lengths into feet first.
You know that there are 12 inches in 1 foot.
So:
24 inches ÷ 12 inches/foot = 2 feet
30 inches ÷ 12 inches/foot = 2.5 feet
Alright, now you can plug in these lengths into the formula.
A = (2) (2.5) = 5 sq. ft.
The question asks you to round, but there is nothing to round, so you are done here.
has no antiderivative in terms of elementary functions (polynomials, exponentials, logarithms, trigonometric functions, etc), but there is a special function defined to fit that role called the error function, 
, where
By the fundamental theorem of calculus, we can see that
which means we have
