Answer:

its A

Step-by-step explanation:

just expand it out

I'm guessing you don't know how to multiply fractions, just do a/b *c/d = ac/bd

and a(b+c) = ab+ ac

A student writes the equation for a line that has a slope of -6 and passes through the point (2, –8).

My name is Ann [436]

Answer:

y-(-8)= -6(x-2)

y+8= -6x+12

y = -6x+ 4

you're mistake was you did +8 in 3rd step but you need to -8 both side becoz y-(-8)= y+8

What is the volume of a right circular cone if the circumference of the base is 125.6 ft and the height is 75 ft.?

Eddi Din [679]

Answer:

Hence the volume of the cone is 31384.52 cubic feet

Step-by-step explanation:

We must first need to understand how the volume of a cone is calculated.

It is simply calculated by multiplying the base area of the cone by the height, and dividing the result by 3.

This is :

Volume of cone = $\frac{\pi r^2 h}{3}$

we are not given the base area of the cone. However, we are given the circumference from which we can get the radius of the base.

Circumference =

$2 \pi r=125.6ft\\r =125.6/2 \pi=19.99ft$

hence the volume of the cone is

$\frac{\pi (19.99)^2 75}{3}=31384.52ft^{3}$

Hence the volume of the cone is 31384.52 cubic feet
