The base of a cone is a circle.

The area of a circle is \pi r^2.

Thus, the area of the base of a cone \pi r^2.

The derivation of the formula for the area of a circle involves a bit of calculus, but if you'd like, I can walk you through it.

Find the x and y intercept for -2x-5y=30
Ahat [919]

Answer:

see below

Step-by-step explanation:

-2x-5y=30

To find the x intercept, set y =0 and solve for x

-2x-5*0=30

-2x = 30

Divide each side by -2

-2x/-2 = 30/-2

x =-15

To find the y intercept, set x =0 and solve for y

-2*0-5y=30

-5y = 30

Divide each side by -5

-5y/-5 = 30/-5

y = -6
