Answer:

C = 62.8 m

Step-by-step explanation:

The circumference formula is C = πd.

Here d = 20 m.  Therefore, the circumference of this circle is C = (20 m)π.

To the nearest 10th, we round off C = (20 m)(3.14159) = C = 62.8 m

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

Trying to understand long division formula. 5 divided by 285.I have it down to 28-25 and i have 035 but why is 35 subtracted by
Sergeeva-Olga [200]

Explanation:

At each step, the product of the quotient digit and the divisor is subtracted from the dividend. This gives you the new dividend.

When the quotient digit is 7, the product of 7 and 5 is subtracted from the dividend. The dividend at that point is 35, so you have 35 - 35 = 0. The 0 is the next dividend. Among other things, that tells you you're done. (Any additional quotient digits will be zero.)
