In terms of pi, what is the volume of the sphere?
9 pi cubic meters
30 pi cubic meters
36 pi cubic meters
72 pi cubic meters

C

Step-by-step explanation:

The volume of a sphere can be found using:

v= 4/3 π r^3

We are given the radius in the picture, and  it is 3. Therefore, we can substitute 3 in for r

v= 4/3 π 3^3

Evaluate the exponent first

v= 4/3 π 27

Since we are finding the answer in terms of pi, we can simply multiply 4/3 and 27 and leave the pi.

v= 36 π  

So, our volume is 36π cubic meters/meters^3, or choice C

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
