Answer:
704π m^2
Step-by-step explanation:
Given data
radius r= 16m
Slant height l= 28m
Required
The surface area of the cone
The expression for the surface area is given as
T.S.A=πrl+πr^2
substitute
T.S.A=π*16*28+π*16^2
T.S.A=448π+256π
T.S.A=704π m^2
Hence the T.S.A is 704π m^2
71 inches X 36 inches = 2556 sq inches
convert sq.feet to sq.inches.
12 sq. feet = 1 sq. inch
2556 sq. feet × 1 sq. inch ÷ 12 sq. feet = 213 sq. inches (sq. feet ÷ sq. feet cancels out the feet variable leaving sq. inch)
