Answer
(-3 * 2p) - (-3 * 3q)
Step-by-step explanation:
I dunno how to explain it but that's it
Exact Surface Area = 378pi
Approximate Surface Area = 1186.92
The approximate surface area uses pi = 3.14
The units are cm^2 or "square cm".
=========================================================
Work Shown:
SA = surface area of cylinder
SA = 2*pi*r^2 + 2*pi*r*h
SA = 2*pi*7^2 + 2*pi*7*20
SA = 2*pi*49 + 2*pi*140
SA = 2*49*pi + 2*140*pi
SA = 98pi + 280pi
SA = 378pi ..... exact surface area
SA = 378*3.14
SA = 1186.92 ..... approximate surface area

Side note: The diameter 14 cuts in half to get the radius r = 7
Answer:
B, C and D
Step-by-step explanation:
dilation is the only transformation that affects the size of the shape, and no transformations affect the shape of the figure.
First find out what 5% of 900 is.
0.05 * 900 = 45
Now subtract this from 900.
900 - 45 = 855
So £900 decreased by 5% is £855.
