Answer:
w=15
Step-by-step explanation:
4w-36=w+9
3w=45
w=15
Answer:
The radius of these cylinders is approximately 1 foot.
Step-by-step explanation:
According to this graph, the volume of the cylinder is directly proportional to its height, that is, radius remains constant. The expression of direct proportionality:
(1)
Where:
- Volume of the cylinder, in cubic feet.
- Height of the cylinder, in feet.
- Proportionality constant, in square feet.
Besides, the proportionality constant is described by this expression:
(2)
Where 
is the radius of the cylinder, in feet.
If we know that 
and 
, then the radius of the cylinder is:
The radius of these cylinders is approximately 1 foot.
Answer- 971.76 yd^3 (btw I used pi not 3.14)
Explanation:
Solve for the volume of the cone
V=pi*r^2*h/3
V=pi*10^2*22/3
V= 2408.55
Next solve for the volume of the sphere
V=4/3*pi*r^3
V=4/3*pi*7^3
V=1436.76
The last step it to subtract the volume of the sphere from the volume of the cone
2408.55-1436.76=971.76
To make calculation easier, we first multiply
1.35 × 100 = 135
then we need to find how many groups of 5 are there in 135.
to do so, we simply take
135 ÷ 5 = 27
therefore, the answer is <u>27.</u>
