What is the formula to find the area of a cone

A=πr(r+h^2+r^2)

- surface area

Step-by-step explanation:

The surface area of a cone is equal to the curved surface area plus the area of the base: π r 2 + π L r , \pi r^2 + \pi L r, πr2+πLr, where r denotes the radius of the base of the cone, and L denotes the slant height of the cone.

πr(r+h^2+r^2)

Step-by-step explanation:

Calculators are god :)

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
