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:
<u>B. y</u>
Step-by-step explanation:
y is the variable because it is a letter representing a number.
If you needed help you would need to show what we would put in the boxes with the arrows but because you didn’t show that we can’t answer and help you
The original messy expression:
2x + 3 + 5x + 6
Add up all the x's: 2x + 5x = 7x
Add up all the plain numbers: 3 + 6 = 9
Re-write the expression: 7x + 9
