Answer:
The volume of the pyramid is not equal to the volume of the cylinder.
Step-by-step explanation:
A right cylinder has the circular cross-sectional area and if the cross-sectional areas of a right pyramid and a right cylinder are the same then the pyramid must be a right circular cone.
Now, the volume of a right cylinder is πr²h and that of a right circular cone is 1/3 πr²h.
Therefore, the radius of the base of the cone and that of the cylinder is the same and their heights are equal to be 5 units, then the volume of the pyramid is not equal to the volume of the cylinder. (Answer)
Answer:
he needs 20.25 bags of sand and it would cost her 80.79
Step-by-step explanation:
150cm*90cm*15cm=202,500cm^3 this is how much sand she needs to fill it
202,500cm^3/10,000cm^3=20.25 this is how many bags he needs
3.99*20.25=80.79 this is how much it'll cost him for all 20.25 bags
Answer:
Ava needs to sell 8 cups of lemonade to earn $24.
Step-by-step explanation:
This is actually just a simple multiplication question. How many times do we need to multiply 3 to get 24? 3 x 8 is 24, and therefore we can conclude Ava needs to sell 8 cups of lemonade to earn $24.
AD BC are parallel because the lines are equal
Answer:
The value of x would 12.2.
Step-by-step explanation:
You have to use the pythagorean theorem to solve this.
a = 5.85 (11.7/2)
b = what we are trying to find
c = 13.5
= 12.1666 which rounds to 12.2
I hope this helps, I apologize if it isn't right.
