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:
- 7 / 4
Step-by-step explanation:
Slope = (y2 - y1) / (x2 - x1)
Slope = (1 - -6) / (-5 - -1)
Slope = - 7 / 4
Answer:
By scoring 240 in the sixth game, Marlon can maintain this exact average
Step-by-step explanation:
The first thing to do here is to calculate the average for the first 5 games.
Mathematically, the average can be calculated by adding all the scores in the games and dividing by 5;
= (210 + 225 + 254 + 231 + 280)/5 = 1200/5 = 240
Now to maintain this average score of 240, we want to know the score she must have in the 6th game.
Let the score be x;
By adding x to the previous total of 1200 before and dividing by the new count of 6, we can work our way to get x.
Mathematically, what we are saying is;
(1200 + x)/6 = 240
6 * 240 = 1200 + x
1440 = 1200 + x
x = 1440 -1200
x = 240
Maybe make a chart or graph showing that information?
