Answer:
The volume of the cylindrical tank is 176.625 cubic feet.
Step-by-step explanation:
Given : The tank is 9 feet high and has a diameter of 5 feet.
To find : Marjorie needs to calculate how much water a cylindrical tank will hold ?
Solution :
The volume of a cylinder is
The diameter is d=5 feet
The radius is
feet.
The height is h=9 feet.
Substitute the value in the formula,
The volume of the cylindrical tank is 176.625 cubic feet.
ANSWER
The slant height is 40cm.
EXPLANATION
The lateral area of a cone is given by:
where r=10cm is the radius of the circle and l is the slant height.
It was also given that, the lateral area is 400π cm²
We substitute the values to get,
We now divide both sides by 10π.
This implies that,
Hence the slant height is 40cm.
