The answer is A because I said so
Answer:
(125/6)π units³
Step-by-step explanation:
The formula for the surface area of a sphere is A = 4πr². Solving this for r² yields:
A
r² = ------
4π
and in this case r² is:
25π
r² = ---------, or 25/4 units²
4π
Thus, the radius, r, is 5/2 units.
The volume of a sphere of radius r is V = (4/3)πr³ units³
Here, that volume is V = (4/3)π(5/2)³ units³
4π 125 units³
= ------ · ------------------ = (125/6)π units³

In a given function y = f(x) = bx - c, the value of y can be determined, if the value of x is known. All we have to do is to substitute the known value for x into the equation in order to determine the value of y.
From the given information:
y = - 180 - 9(x)
y = -180 - 9(-15)
y = -180 + 135
y = -45

Answer:
Not an arithmetic sequence
Step-by-step explanation:
For the sequence to be arithmetic there must be a common difference between consecutive terms.
- 7 - (- 3) = - 7 + 3 = - 4
- 10 - (- 7) = - 10 + 7 = - 3
- 14 - (- 10) = - 14 + 10 = - 4
The differences are not common , hence not an arithmetic sequence
