Answer:
A=777.54
Step-by-step explanation:
What you do is use the formula which is
a=2pirh+2pir^2.
The radius is half the diameter and the diameter is 15 so you take 15 and divide it by 2 to get 7.5.
The height is 9 m.
A=2(3.14)(7.5)(9)+2(3.14)(7.5)^2=777.54 m.
Answer:
777.15 m^2
Step-by-step explanation:
To find the surface area of a cylinder
SA = 2 pi r h + 2 pi r^2
The area of the sides Plus the area of the top and bottom
We know the diameter is 15 so the radius is 1/2 (15) = 7.5
SA = 2 * pi * (7.5) * 9 + 2 * pi * (7.5)^2
= 135pi + 112.5pi
247.5 pi
Approximating pi with 3.14
247.5 (3.14)
777.15 m^2

Answer: 0.41
Step-by-step explanation: 0.59 is 59%. To find the percentage of chance that it will not rain, you subtract 1 (which is 100%) minus 0.59. You get an answer of 0.41 (or 41% if you prefer.)
Answer:
8 and 1/4
Step-by-step explanation:
10 3/4 - 2 1/2
3/4 - 1/2 = 1/4
10 - 2 = 8
Answer:
-18 x 4 = -72
Step-by-step explanation:
a negative times a positive is a negative number.
Answer:
True
Step-by-step explanation:
So the radius would be 5 (as you times it by 2 to get 10)
Therefore
2a=10 is the same as what the circle with diameter d=2r=10
Hope This Helped and GOOD LUCK!!!!!!! :D
