How many times can 8 go into 60
nignag [31]

The correct answers are:

(1) If EXACT number is required, then 7.5.

(2) If multiple of 8 is required then the answer will be 7 times with a remainder of 4.

Explanation:

First you need to express it in the form of equation to make things simpler as follows:

8 * y = 60

We need to find y; to do so, divide 60 by 8:

y = \frac{60}{8}

y = 7.5

Now if you want to find the whole number, then the answer will be 7 times, with 4 left over.

A cone has a volume of 5 cubic inches. What is the volume of a cylinder that the cone fits exactly inside of?
Pie

Answer:

15 in^{3}

Step-by-step explanation:

Given:

Volume of Cone= 5 inch ^{3}

Solution:

Formula:

Volume of Cone =\frac{1}{3} \pi r^{2} h

Volume of Cylinder= \pi r^{2} h

\therefore We can say that

Volume of Cone = \frac{1}{3} \times Volume of Cylinder

\therefore Volume of cylinder = 3 \times Volume of Cone

Now Substituting given data we get

Volume of Cylinder= 3\times5

Volume of Cylinder= 15 in^3
