Answer:
25 seconds
Step-by-step explanation:
The radius of a hailstorm varies directly
with the amount of time that it was in a cloud.
Radius = k x Time (in the cloud)
k is the constant of proportionality
R = k x T
0.5 = k x 10
k = 0.5/10
k = 0.05
Formula: R = 0.05 x T
1.25 = 0.05 x T
Time = 1.25/0.05
Time = 25 seconds.
Hope this helps :) !
Answer:
The surface = pi*10cm2
Step-by-step explanation:
The area of any rectangle is Base * Height,
We know that the square originally has 10cm High, when is rolled to form a cylinder, it's new shape has a bottom side that is equals to a circle.
The length of a circle is 2*pi*Radio= pi*Diameter.
Since the square has the same length in each side, we know that pi*Diameter= 10cm*pi
The surface (area) of the cylinder is= Base * Height= 10cm*10cm*pi

Answer:
AC = 52
Step-by-step explanation:
Add the segment lengths together.
AB + BC = AC
22 + 30 = 52
