First you need to find the radius. To do that you need to divide the diameter by two;
45 / 2 = 22.5
Then you plug the radius in the formula for a sphere. Which is...
V = (4 / 3)πr^3
First you need to find the volume with out pi
V = (4/3) π (45)^3
V= π (4/3) (91,125)
Your answer with out pi is...
V= (68,343.75) π cm^3
And with pi is...
V = 214,708.22 cm^3
Answer:
64π
Step-by-step explanation:
Since the diameter of the circle is 16, the radius is half of that which is 8.
Area = πr² = 64π
answer: 27.9 pounds
work: the question is asking how many pounds he bought total, so add the potato and the carrots, and you have your answer. 24.37 + 3.53 = 27.9
