Answer:
2.4
Step-by-step explanation:
From the Euclidian theorem TR*TS = RS*h
3*4 = 5*h
12 = 5h divide both sides by 5
2.4 = h
Answer:
953.78 in³
Step-by-step explanation:
Area of circle = πr²
The area of the base
= 3.14×(9÷2)²
= 63.585 in²
The capacity of the container
= 63.585×15
= 953.775 in³
Answer:
1 : 1
Step-by-step explanation:
When a circle is inscribed in a cylinder, the height of the cylinder is equal to the diameter of the sphere and the radius of the cylinder is same as that of the sphere.
Let the radius of sphere is r.
height of cylinder, h = 2r
radius of cylinder = r
Surface area of sphere, A = 4πr²
lateral surface area of cylinder, A' = 2 πrh
A' = 2πr x 2r = 4πr²
The ratio of surface area of sphere to the lateral surface area of cylinder is 1 : 1.
