1. what is the height of a cone whose radius is 3 cm and volume is 900 cm3?
1 answer:
R = 3cm
V = 900 cm^3
V = pi * r^2 * h / 3
900 = (22/7) * 3^2 * h/3
h = (900*3*7) / 22 / 3^2
h = 18900 / 22 / 9
h = 95.45 cm

Answer:20
Step-by-step explanation:
Reduce 35/100 to 7/20 by dividing both sides by 5.
2/5 is bigger than 7/20.
2/5 > 7/20 or 2/5 > 35/100 if you leave it unsimplified
Hope this helps :)
