5 The volume, V, of a cylinder is equal to the area of its base, B, times its height, h. If
the diameter of a cylinder is 21 feet and its
height is 4.2 feet, which expression
represents Vin cubic meters?
21 feet
4.2 feet
A 217(2.1)
B 4.27(10.5)
C (4.2)
D None of these

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!

3/20

step-by-step explanation:

well, there are 20 outcomes, and 3 of them you want. so, 3/20
