Find the volume of a right circular cone that has a height of 2.5 m and a base with a diameter of 18.6 m. Round your answer to t

dem82 [27]

Answer:

226.4 m³.

Step-by-step explanation:

The volume of a right cone with a circular base is:

$\displaystyle V = \frac{1}{3} \pi\cdot r^{2}\cdot h$ ,

where

$V$ is the volume of the cone,
$r$ is the radius of the cone,
and $h$ is the height of the cone.

The radius of the circular base is one-half its diameter.

$\displaystyle r= \frac{1}{2}h=9.3\;\text{m}$ .

$\displaystyle V = \frac{1}{3} \pi\cdot r^{2}\cdot h = \frac{1}{3} \pi \times 9.3^{2} \times 2.5 \approx 226.4\;\text{m}^{3}$ .

-11 - 5a = 6(5a + 4) but I really need it in mathematical form.

ella [17]

Answer:

Step-by-step explanation:

In this equation what is strange is probably using the letter a as the unknown, but this is a matter of choice we could have calle y or z for that matter. Then we will treat it ans any other equation and solve it.

-11 -5a = 6(5a+4)

-11 -5a= 30a + 24

-11 - 24 = 30a + 5a (placing the unknown a in the rght side and the numbers in the left to solve the equation)

- 35 = 35a

-35/35 = a

- 1= a
