Answer:
addison all the way
Step-by-step explanation:
Formula: V = (2/3) π r 3.
Radius is 3cm.
So, now we can plug it in to solve for the volume.
V = (2/3) π 3^3
First, let's multiply 3^3.
3^3 = 27
Then, 27 x π = 84.82
After, multiply by 2/3.
84.82 x 2/3 = 56.55
Lastly, round 56.55 to the nearest tenth of a cubic centimeter.
56.55 = 56.6
Therefore the volume of a hemisphere with a radius of 3cm is 56.6cm^3.
Answer:
(d) 428,820,000 pounds of garbage
Step-by-step explanation:
Your calculator or spreadsheet can give you the product of two numbers expressed in scientific notation.
(1.643×10^3 lb/resident) × (2.61×10^5 residents) = 4.28823×10^(3+5) lb
≈ 428.82×10^6 lb
= 428,820,000 lb . . . of garbage
Answer:
x=8
Step-by-step explanation:
the y-value in the first pair decreased by half, so the x-value must double due to inverse variation.
