Answer: V= 100.48 m^3 or in terms of Pi V = 32 π m^3
Step-by-step explanation:
V = πr^2h
V = π(2)^2(8)
V = π(4)(8)
V = 100.48
or
V = π (4)(8)
V = 32 π m^3
The answer is: [B]: " 1.75 * 10⁻¹⁵ " .

Note:

(2.5 * 10</span>⁻¹⁰<span>)(7 * 10</span>⁻⁶) = (2.5)*(7) *(10⁻¹⁰) *(10⁻⁶)
Note: (10⁻¹⁰) *(10⁻⁶) = 10⁽⁻¹⁰⁾⁺⁽⁻⁶⁾ = 10⁽⁻¹⁰⁻⁶⁾ = 10⁽⁻¹⁶⁾
{Note: xᵃ * xᵇ = x⁽ᵃ⁺ᵇ⁾ } ; ===> Property of exponents;
So; (2.5)*(7) *(10⁻¹⁰) *(10⁻⁶) = (2.5)*(7) * 10⁽⁻¹⁶⁾ ;
2.5 * 7 = 17.5 ;
so; (2.5)*(7) * 10⁽⁻¹⁶⁾ = 17.5 * 10⁻¹⁶

SInce the answer choices are given in scientific notation;
in terms of "1.75"; we rewrite this value in such format to get the equivalent value; by dividing by "10" ; to get: "1.75 * 10⁻¹⁵ " (note: this value is equivalent; since the number of "zeros" is adjusted.

It's simple, if you understand. Let's see.
y= the total cost of everything.
x=the total amount of hours spent on the contract.
It's simple!!
$140 is the base line. It never changes. So, we begin with $140. Every hour Luigi works, he charges $25. So $140+$25x. Finally, our total amount is y, so $140+$25x=y. abracadabra!!
