Answer:

C) 45.53in cubed.

Step-by-step explanation:

One formula for finding circumference is C=r2(pi).

So, if you plug in the numbers,

= C=7.25(2)(3.14)

= C=14.5(3.14)

= C=45.53

So, the answer is 45.53in cubed after multiplying all of the numbers.

Hope this helps :)

(I'm not sure if it's right though because the answer is cubed.)

Virty [35]

To multiply fraction do top x top and bottom x bottom
so convert $2 \frac{5}{6}$ into $\frac{17}{6}$
then do $\frac{3}{10} * \frac{17}{6} = \frac{3*17}{10*6} = \frac{51}{60} = \frac{17}{20}$

A right circular cylinder has a volume of 1 cubic meter and a height of 0.6 meters what is the radius of the cylinder to the nea

lapo4ka [179]

The volume formula of a cylinder is :

$V=\pi r^2h$

From the problem, the volume is 1 m^3 and the height is 0.6 m.

Substitute the given to the formula :

$\begin{gathered} 1=\pi r^2(0.6) \\ 1=3.14(0.6)r^2 \\ r^2=0.53 \end{gathered}$

Take the square root of both sides of the equation :

$\begin{gathered} r^2=0.53 \\ r=\sqrt[]{0.53} \\ r=0.728 \end{gathered}$

The answer is r = 0.728 m
