100.77 round to the nearest tenth of a square mile

7 0

The tenth place is the one just to the right of the 0. This means that we have to look at the hundreths place which is 2 places to the right of the 0. If the number is greater than or equal to 5 then we round up. The number in the hundreths place is 7, which is above 5 we round the tenths place up to 8.

This would make your answer 100.8

Find the volume of a cylinder with a diameter of 6 inches and a height that is three times the radius. Use pi on your calculator

Virty [35]

ANSWER
$V=254.47in^3$

EXPLANATION

The volume of a cylinder is given by the formula:

$V=\pi \: {r}^{2} h$

The given cylinder has diameter 6. This means that, the radius is

$r = \frac{6}{2}$

$r = 3cm$

The is height is

$h = 3r$

$h = 3(3) = 9cm$

We substitute the values into the formula to obtain;

$V=\pi \: {3}^{2} \times 9$

$V=81\pi$

$V=254.46900494$

The volume is $254.47in^3$ to the nearest hundredth
