Answer:
40/3 pi
Step-by-step explanation:
Volume of a cone = 1/3 *pi*h*r^2 , where h = height, and r = radius.
diameter = 2 radius, so radius = 8/2 = 4
The height = 10, so plug these values into the equation:
1/3 * pi * 10 * 4 =
40/3 pi
We can use the rule of three to figure out what's 5% of 79:
100/79=5/x
x= (79*5/100)=3.95
Let's add said 5% to 79:
79+3.95=82.95
Use Pythagoras:
x² = (8.5)² + (5)²
x = √[(8.5)² + (5)²]
Answer:
The volume is 1436.8
.
Step-by-step explanation:
-To find the volume of a sphere, you need the formula:
-Use the radius for the formula:
-Then, you solve:
× 
× 
× 
-Round the answer to the nearest tenth:
So, therefore the volume is 1436.8 .
So if she estimated 45 and has 41, then the error is 45-41=4
so find what percent=4/45
divide
4/45=0.0888888
percent=parts out of 100 so
x/100=x%
so 0.0888/1 times 100/100=8.8888/100
the answer is 8.88888% or rounded up is 8.9%
the answer is C
