Acone has a height of 7 ft and a radius of 4 ft. Which equation can find the volume of the cone?

Marina86 [1]

Answer:

Volume of the cone = $117.06\,feet^3$

Step-by-step explanation:

Height of the cone = $7\,feet$

Radius of the cone = $4\,feet$

Volume of a cone is:

$\pi \times r^2\times \dfrac{h}{3}$

As, $\pi =\dfrac{22}{7} =3.14$

Volume is:

$=3.14\times(4\times 4)\times \dfrac{7}{3}\\\\ =3.14\times 16 \times 2.33\\\\=3.14\times 37.28\\\\=117.06\,feet^3$

The volume of the cone is: $117.06\,feet^3$

Major arc CBD measures 300°. Which is the radian measure of its corresponding central angle? radians radians radians radians

morpeh [17]

Answer:

$\frac{5}{3}\pi\ radians$

Step-by-step explanation:

we know that

If the measures of the major arc CBD is equal to $300$ degrees

then

the measure of its corresponding central angle is equal to $300$ degrees

Convert degrees to radians

Remember that

$180\°=\pi \ radians$

so by proportion

Convert $300\°$ to radians

$\frac{\pi}{180}\frac{radians}{degrees} =\frac{x}{300}\frac{radians}{degrees}\\ \\x=300\pi /180\\ \\x=\frac{5}{3}\pi\ radians$
