Answer: 2450.44 ft
Step-by-step explanation:
Formula for SA of a cylinder: A=2*pi*r*h+2*pi*r^2
Formula for radius: diameter/2
Plug height, 17, radius, 13, and pi, 3.14, into the formula above.
= 2450.44 ft
225 miles / 45 miles/hr = 5hr
Answer:
it has to equal -1 x= to -1 parenthesees
1 times -1= -1 its true for that 1 answer but not the others
Answer:
Option (4).
Step-by-step explanation:
Outer diameter of the hollow metallic ball = 10 centimeters
Outer radius of this ball =
= 5 cm
Volume of the outer ball
= 
= 
Inner radius of the hollow metallic ball = (5 - 1) = 4 cm
Volume of the inner hollow ball
= 
Volume of the metal used in the metallic ball = 
= 
= ![\frac{4}{3}\pi [(5)^3-(4)^3]](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B3%7D%5Cpi%20%5B%285%29%5E3-%284%29%5E3%5D)
Therefore, expression given in option (4) will be used to measure the volume of the hollow metallic ball.
