The answer is -8 because -4x2 is -8
Answer: Choice A
The volume expression is 4/3 times pi times (3x)^3
===================================================
The volume of a sphere is found through the formula
V = (4/3)*pi*r^3
so we start with the fraction 4/3, multiply it with pi, and then multiply it with r^3
In this case, the radius is r = 3x because this is half of the diameter d = 6x
We simply replace the r with 3x in that formula above
V = (4/3)*pi*r^3
V = (4/3)*pi*( r )^3
V = (4/3)*pi*(3x)^3 ... replace r with 3x
1 = 90
2 = 65
3 = 65
4 = 25
90+25=115
180-115=65
have a merry christmas :)

Answer:
Step-by-step explanation:
Given rectangle JKLM
As per graph, the rectangle J'K'L'M' is the transformation of JKLM
Based on one of the points we can calculate the transformation rule:
<u>Let's use points K and K'</u>
- K((-4, -8) → K'(6, -5)
- 6 - (-4) = 10
- -5 - (-8) = 3
<u>So the rule is </u>
- (x', y') → (x + 10, y +3)
<u>Trapezoid STUV:</u>
<u>Applying same rule:</u>
- T' = (6 + 10, 4 +3) = (16, 7)
