Answer:
C
Step-by-step explanation:
1. 12+6 = 18 so that's the diameter of the big circle
2. next we take the square of 18 and multiply it by pi (324x3.14)
3. answer: 1017.36
7 1/4 + 5 3/5 = 12 17/20 You can't reduce it no more.

Answer:
$4866.61
Step-by-step explanation:
Answer:
Part 1) The volume of the ball is 256 cm³
Part 2) The radius of the ball is 3.94 cm
Step-by-step explanation:
Part 1) we know that
The density is equal to divide the mass by the volume
D=m/V
Solve for the volume
The volume is equal to divide the mass by the density
V=m/D
In this problem we have
m=128 g
D=0.5 g/cm³
substitute
V=128/0.5=256 cm³
Part 2) what is the radius of the ball?
we know that
The volume of the sphere (ball) is equal to

we have

assume

substitute and solve for r
