Answer:
28.6 ft
Step-by-step explanation:
Given an hemisphere of volume ![49037 ft^3](https://tex.z-dn.net/?f=49037%20ft%5E3)
Volume of a Hemisphere of radius r ![=\frac{2}{3}\pi r^3](https://tex.z-dn.net/?f=%3D%5Cfrac%7B2%7D%7B3%7D%5Cpi%20r%5E3)
Therefore:
![\frac{2}{3}\pi r^3=49037 \\r^3=49037 X \frac{3}{2 \pi}\\r=\sqrt[3]{49037 X \frac{3}{2 \pi}} \\r=28.6\: foot](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D%5Cpi%20r%5E3%3D49037%20%5C%5Cr%5E3%3D49037%20X%20%5Cfrac%7B3%7D%7B2%20%5Cpi%7D%5C%5Cr%3D%5Csqrt%5B3%5D%7B49037%20X%20%5Cfrac%7B3%7D%7B2%20%5Cpi%7D%7D%20%5C%5Cr%3D28.6%5C%3A%20foot)
The radius of the hemisphere is 28.6 foot to the nearest tenth.
Answer:
Tom weighs 70 pounds
Step-by-step explanation:
first, you have to set up your equation which would be, x + 3x = 280.
The x stands for Tom's weight and the 3x stands for three times Tom's weight for the dad. You would then add your like terms, then divide by 4 to get 70.
x + 3x = 280
4x = 280
280/4 = 70
x = 70
Hope this helps!
