Answer:
Step-by-step explanation:
1. ¹/₃ × π × r² × l:so 33.9.29cm³
2. π × r² × l:so π x 2² x 3.5=43.98ft³
3.¹/₃ × π × r² × l, to get the radius from diameter you divide the diameter by 2 so it would look like: ¹/₃ × π x 4² x 12= 201.06in³
4.352cm³
5. cone: 1/3 πr²h
Cylinder: πr²h
cone : 33 Cylinder = 3 x 33 = 99 in³
Hello!
To solve this you have to find the ratio between the two cylinders
Cylinder 1 height is 30
Cylinder 2 height is 20
this is a 30:20 ratio
This can be reduced to a 3:2 ratio
Now you look for one that are also equal to 3:2
3 * 7 = 21
2 * 7 = 14
The answers are 3:2 and 21:14
Hope this helps!
Answer:
27
Step-by-step explanation:
If k/3 = 9
K must be 27
because 9*3=27
and to check we can do
27/3
and 27/3 = 7
