Step-by-step explanation:
Edit:
a is 18
b is 36
c is 18
d is 18 times sqr root of 3
Answer:
28
Step-by-step explanation:
x-10+2=20
add -10 and 2 together to simplify the equation
x-8=20
add 8 to both sides to isolate x
x=28

Okay Bright, so the central angle is 36 degrees, so according to the formula you have on the top of the screen, we have to do 36/360, which is 1/10 or 0/1.
Then we multiply that by the radius squared. 12^2 = 144.
Finally, we multiply 144 by 0.1, which is 14.4. So
our answer is H. 14.4
.
Notice that we don't multiply the radius squared by

, since the answers are in terms of

.
Hope this helped!
What do you need help with?
V = 4/3 (pi) r^3
ball with radius of 18 cm...
V = 4/3(3.14)(18^3)
V = 4/3(3.14)(5832)
V = 24429.02
ball with radius of 12...
V = 4/3(3.14)(12^3)
V = 4/3(3.14)(1728)
V = 7238.23
24429.02 - 7238.23 = 17190.79 greater <====
