I think the answer is *1,008* I hope I get it right
The total Surface Area of a right Cone is the sum of the area of its base and the lateral (side) surface.
The formula for the total surface area of a right cone is
Where r is the radius, and l is the slant height
Step-by-step explanation:
Find 2r:
11 x 11 = 121
Multiply 2r with pi:
121 x 3.141592654 = 380.1327111
= 380.13 (Nearest hundredth)
I kind of forgot my 6th grade geometry, so I'm sorry if it is wrong.
