The answer is 12π.
To get the volume of the cone, we need the height. The radius is given.
V = πr² × (h/3)
The total surface area of the cone is:
SA = πr² + πrl where r is radius and l is slant height
24π = π(3)² + π(3)(l)
24π = 9π + 3πl
24π - 9π = 3πl
15π = 3πl
l = 15π / 3π
l = 5
Using Phytagoras, we can calculate the height of the cone:
l² = h² + r²
5² = h² + 3²
25 - 9 = h²
h = √16
h = 4
Therefore the volume is:
V = π(3)² × (4 / 3)
V = 3π × 4
V = 12π
Given
The parallelogram,
To find the area of the parallelogram.
Explanation:
It is given that,
The base of the parallelogram is 10 inches.
And, the height of the parallelogram is 5 inches.
Therefore,
Hence, the area of the given parallelogram is 50 in^2.
Answer:
Heres the answer
Step-by-step explanation:
To calculate the ratio of an amount we divide the amount by total number of parts in the ratio then multiply the answer by original ratio.
