The SA formula to find a right cone is area of the base x 1/2 (perimeter)(slant height)
To find the area of the base you do radius squared x pi
Radius=11
So 121pi is area of the base
Perimeter=circumference of the circle
So perimeter=24pi
So 121pi x 1/2 (12pi)(6)
12 x 6=72pi/2=36pi
121pi x 36pi= 4356pi
Answer: 4356pi
Ur missing numbers are -2, 6, and 36
Since the center point is (-2,6), the numbers are reversed in the equation to: (x+2) or(x- -2) and (y-6)
The radius is 6 units so u square it to get 36
S + 2.8 = 6.59
s = ?
To solve for s use the inverse operation of addition, which is subtraction.
s + 2.8 = 6.59
6.59 - 2.8 = s
6.59 - 2.8 = 3.79
s = 3.79
Check:
s + 2.8 = 6.59
s = 3.79
3.79 + 2.8 = ?
3.79 + 2.8 = 6.59
Correct!
This proves: s = 3.79 ;)
