Answer:
74.33
Step-by-step explanation:
We need to figure out the surface area. The formula for surface area is A=2πrh+2πr2
We substitute r with the radius of this cylinder and the h represents the height of this cylinder. The height we can find because we just add the diameters of the tennis balls. So 2.6*3 = 7.8. Then we get the radius, which will just be the radius of a sphere, so 1.3. Then we plug them into the formula, giving us 74.33
Answer:
A
Step-by-step explanation:
Substitue 15 into the x value and complete the equation.
This is because 2,280 is the original distance. 15 would be the hours and 60 would be how many miles per hour. So we multiply 15 and 60 and get 900, this is how many total miles they have driven. But when we subtract that number from 2,280, and we get 1,380, this is how many miles they have left.
Answer:
34
Step-by-step explanation:
52-35 = 17
$17 divided by $0.50 = 34 texst messages
-1 is the first line after 0
8 is 3rd line one the right side after 5
-11 is just first line after 10..
I hope U understand
9+10=19
proof, 9=1 plus 1 9 times (to lazy to write it out)
10=1 plus 1 10 times(to lazy)
so 1+1+1+1+1+1+1+1+1 + 1+1+1+1+1+1+1+1+1+<span>1 = 19</span>
