We know that
Part 1)
[surface area of a cone without base]=<span>π*r*l
r=3 in
l=slant height ----> 6 in
</span>[surface area of a cone without base]=π*3*6------> 56.52 in²
[surface area of a cylinder]=π*r²+2*π*r*h------> only one base
r=3 in
h=5 in
[surface area of a cylinder]=π*r²+2*π*r*h
[surface area of a cylinder]=π*3²+2*π*3*5-----> 122.46 in²
[surface area of the composite figure]=56.52+122.46-----> 178.98 in²
the answer Part A) is
178.98 in²
Part B)
[surface area of the composite figure]
=12*16+2*12*7+2*16*7+5*12+5*16+13*16----> 932 ft²
the answer Part B) is
932 ft²
Answer:
Is this like a random question or did you forget to put something? But if it is then B ig
Step-by-step explanation:
Answer:
Step-by-step explanation:
Plug each value of x into the equation and solve for the corresponding y value.
When x = -1, y = (-1)²-2(-1) = 3
When x = 0, y = 0² - 2(0) = 0
You can finish from here.
Answer:
62.8 inches
Step-by-step explanation:
because C= 2pi
and 10 times 2 is 20 and 20 times 3.14 is 62.8
