Answer:
B
Step-by-step explanation:
you have probably finished the quiz by now but anyway
so first flip the picture so that u see the cylinder standing on its base
12 is the diameter and 8 the height
12/2 = 6=radius
finally u do
πr
h
3.14*
*8
**i simplified π so the answer will be 904.32**

C because the formula to find the are of a circle is A=(pi) * radius^2. To find the radius from diameter, just divide by two. So 60/2= 30 so now you can just plug in and 30 * 30 is 900 and 900 * pi, or 3.1415926535, is about 2827
It's one of the ways to count it:
3/4 (n + 3) = 9
3/4n + 3/4 * 3 = 9
3/4n + 9/4 = 9
3/4n + 2 1/4 = 9 / - 2 1/4 (both sides)
3/4n = 6 3/4 / : 3/4 (both sides)
n = 9
Answer:
54
Step-by-step explanation:
multiply by 1.8 and add 32
12*1.8=21.6
21.6+32=53.6
53.6 rounded = 54
