Answer:
SA. = 62.8 +87.92= 150.72
Step-by-step explanation:
surface area of cone without base = pi*r*s = 3.14 * 2* 10 = 62.8
Surface area of cylinder without base = 2*pi*r*h + pi*r*r
= 2* 3.14 * 2 * 6 + 3.14*2*2
= 75.36 + 12.56 = 87.92
SA. = 62.8 +87.92= 150.72
The required surface area of the solid is 150.72.
Given
slant length of cone = 10
length of cylinder = 6
Common radius = 2
Surface area is defined as the area of the surface that are uncovered.
Surface area of cone = π x r xs
= 3.14 x 2 x 10
= 62.82
Surface area of cylinder = 2 x π x r x h + π x r²
= 2 x 3.14 x 2 x 6 + 3.14 x 2 x 2
= 87.9
The required surface area of solid= surface area of cone + surface area of cylinder
= 62.80 + 87.9
= 150.72
Thus, the required surface area of the solid is 150.72.
