Answer:
The volume of a cone is 1/3 of the volume of the cylinder.
Step-by-step explanation:
The formula for a cylinder is:
V = bh
For a cone:
V = 1/3(bh)
If the radius of both are the same, then the area of the base is the same. The height is also constant, therefore:
The volume of a cone is 1/3 the volume of the cylinder.
--------------------------
Example to prove:
Given, radius 2 and height 15:
Cylinder: V = bh (b = πr²)
V = 4π × 15
V = 60π u³
Cone: V = 1/3 (bh)
V = 1/3 (4π × 15)
V = 20π u³
Volume of the cone is 942 cm³
Step-by-step explanation:
- Step 1: Find the volume of the cone given base area = 78.5 cm² and height = 12 cm
Volume of the cone = Base area × Height
= 78.5 × 12 = 942 cm³
Answer:2
Step-by-step explanation:
Well when you multiply a negative integer by a negative integer, it'll all ways be positive.
For example; - 34 × - 7 = 34 × 7 = (238)
We need to find how many sets of 5 are in 625.
625÷5= 125
So, Harley will need 125 pallets for 625 bags of cement.
