Answer:
4188.8 cm^3
Step-by-step explanation:
We can calculate the volume of a sphere by using the following equation:
(r=radius)
so let's just plug in what we know
4/3(pi)(10)^3
we can calculate this with a calculator to get 4188.8 cm^3.
B and C
3^3 = 27
the cubed root of 27 is 3
<span>3x(x^2+4)
= 3x^3 + 12x

<u>Given Function is</u>
- f ( x ) = 7x - 7 ------- eqn ( 1 )
<u>Now , put the value of x = 8 in eqn ( 1 )</u>
- f ( 8 ) = 7 ( 8 ) - 7
- f ( 8 ) = 56 - 7
- f ( 8 ) = 49 ------- eqn ( 2 )
<u>Now , put the value of x = 4 in eqn ( 1 )</u>
- f ( 4 ) = 7 ( 4 ) - 7
- f ( 4 ) = 28 - 7
- f ( 4 ) = 21 ------- eqn ( 3 )
<h3 />
<u>From eqn ( 2 ) nd eqn ( 3 ) we get,</u>
- f ( 8 ) + f ( 4 )
- 49 + 21
- 70
Hope Helps! :)
