8^2 is 64 and 2^2 is 4. When you add them together you get 68.
(8+2)^2 is the same as 10^2 which is 100.
68≠100
just do it like nike said
Answer:
-35a
Step-by-step explanation:
Here, you just distribute: -7 * 5a
= -35a
We have been given that the volume of a cone is 113.04 cubic mm. We are asked to find the approximate volume of a sphere that has the same height and a circular base with the same diameter.
We know that volume of cone is
.
The height is equal to the diameter. We know that diameter is 2 times radius, so we can represent this information in an equation as:

Upon substituting
in volume of cone, we will get:


We know that volume of sphere is
.
Upon comparing volume of cone with volume of sphere, we can see that volume of sphere is 2 times the volume of cone.

Since
, so volume of sphere would be:


Therefore, volume of sphere would be 226.08 cubic mm.
