What is the surface area of the figure shown? (Use 3.14 for π.)
Ivanshal [37]
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

Which pair of numbers have a GCF of 7?
Inessa [10]
A GCF is the greatest common factor. It is the largest number that fits into other numbers. A seven cannot fit into a number smaller than itself, that doesn't work. Try to fit 7 into a smaller number like 4, it doesn't work.

Option A is 21 and 3 and Option C is 7 and 1. Those can be eliminated because 7 is larger than 3 and 1.

Option B is 7, 14. 7 Is the largest number that goes into 7 and it goes into 14. So B works.

28 and 7 is Option D. 7 is the largest number that goes into 7 and it goes into 28, so D works.
