sphere and a cylinder have the same radius and height. The volume of the cylinder is 11 feet cubed. A sphere with height h and r
Fed [463]

Step-by-step explanation:

We have, a sphere and a cylinder have the same radius and height. The volume of the cylinder, V_c=11\ ft^3

The volume of sphere is : V_s=\dfrac{4}{3}\pi r^3

The volume of cylinder is : V_c=\pi r^2h

Dividing the volume of sphere and the volume and cylinder, such that,

\dfrac{V_s}{V_c}=\dfrac{4\pi r^3}{3\pi r^2h}

As r = h

\dfrac{V_s}{V_c}=\dfrac{4}{3}\\\\V_s=\dfrac{4V_c}{3}\\\\V_s=\dfrac{4}{3}\times 11

So, the volume of sphere is (four-third) of 11. therefore, the correct option is (A).

Question is in picture :) also pls explain (if u can)
fenix001 [56]

The m’s would all be the same number.Another way of adding the same number to each other would be to multiply that number by the number of times you want to add it to each other.

With m + m + m you are adding it 3 times.

So instead multiply m by 3:

The answer is 3m

2x+8=y if x=6 then what is the value of y?
Norma-Jean [14]

Answer:

20

Step-by-step explanation:

If x = 6 the problem should look like this:

2 (x) + 8 = y -> place the 6 where x is.

2 (6) + 8 = y -> remember () means to multiply.

2 times 6 , add 8 , equals y

12 + 8 =y -> 12 +8 equals 20

20 = y

I hope this helps!!
