1.a sphere with a radius of three units
By definition, the volume of a sphere is:
Substituting values we have:
Rewriting we have:
2.a cone with a diameter of twelve units and a height of three units
By definition, the volume of a cone is given by:
Substituting values we have:
Rewriting we have:
In this question, the speed of the dolphin is already given, but the unit is different. The speed of the dolphin is given as 40 miles per hour and it has to be converted to feet per hour.
We already know that 1 mile = 5280 feet
Then
40 mile = 5280 * 40 feet
= 211200 feet
So the speed in feet per hour will be 211200 feet per hour. I hope the procedure is clear enough for you to understand. You can always use this method for solving similar problems without requiring any help from outside.
87 24/25.......24/25 = 0.96......answer is 87.96
224 7/10....7/10 = 0.7....answer is 224.7
686 49/50...49/50 = 0.98...answer is 686.98
Answer:
r = 5
Step-by-step explanation:
The formula for volume of a cone is
h = 6
V = 50π
r = 5
Answer: x = 5
explanation:
divide both sides by 5 to get x = 5
