Answer:
47.1: 50.24
Step-by-step explanation:
V= πr²(h/3)
= 3.14 x 3²(5/3)
= 3.14 x 9(5/3)
= 3.14 x 3(5)
= 3.14 x 15= 47.1
Volume of cylinder
V = πr²h
V = 3.14 x 2² x 4 = 3.14 x 4 x 4 = 3.14 x 16 = 50.24
the ratio of Volume of Cone to Cylinder
47.1: 50.24 = 47.1/50.24 =

Let First Sphere be the Original Sphere
its Radius be : r
We know that Surface Area of the Sphere is : 4π × (radius)²
⇒ Surface Area of the Original Sphere = 4πr²
Given : The Radius of Original Sphere is Doubled
Let the Sphere whose Radius is Doubled be New Sphere
⇒ Surface of the New Sphere = 4π × (2r)² = 4π × 4 × r²
But we know that : 4πr² is the Surface Area of Original Sphere
⇒ Surface of the New Sphere = 4 × Original Sphere
⇒ If the Radius the Sphere is Doubled, the Surface Area would be enlarged by factor : 4
Answer:
f(10)=-217
Step-by-step explanation:
F(10)=-2*10^2 + 17= -2*100+17= -200+17=-217
