Answer:
<em>Volume: Option A - Around 85.33 (in^3)</em>
Step-by-step explanation:
Let us take a look at the problem. Here we are given the circumference of the bowling ball, provided it is in the shape of a sphere.
Our first step can be to note the formula of circumference, applicable to both a sphere and a circle:
C = 2 * π * r - Where r = radius
Now let us substitute the known value of the circumference as to solve for r, or the radius:
(8π) = 2πr
r = 8π/2π
r = 4
Now take a look at the spherical formula for volume of a sphere:
V = 4/3 * π * r^3 - Where r is yet again the radius
Let us substitute the known value of the radius as to solve for the volume, or in other words to solve for the answer:
V = 4/3 * π * (4)^3
V = 4/3 * π * 64
V = 256/3 * π
V = (Around) 85.33π (in)^3
*Don't forget the units
Answer:
option D
Step-by-step explanation:
To get equivalent expression we need to remove the parenthesis
multiply negative sign inside the parenthesis
when we multiply negative and negative it becomes positive.
So the expression becomes
So, option D is the equivalent expression

Answer:
20%
Step-by-step explanation:
The percentage increase is ...
percent change = (new/old -1) × 100% = (36/30 -1)×100% = 1/5×100% = 20%
The worker's income increased 20%.
The range of any data set is always the biggest number - the smallest number. In this case the equation is 34-8=26. So the range would be 26.
Hope this helps
