Answer:
13 mm
Step-by-step explanation:
we use the cylinder surface area formula to find the height.
SA = 2πrh + 2πr² we adjust the formula for h
SA - 2πr² / 2πr = h Now we can plug in the numbers
(715.92 - 2 * 3.14 * 6²) / 2 * 3.14 * 6
h = 13 mm
answer b
please mark as brilliant
first function:
second one:
now the intersection:
-4x+10=-3x+2
x=8
then y
y = -4×8+10 = -22
so it's
(8,-22)
