We have been given that the volume of a cone is 113.04 cubic mm. We are asked to find the approximate volume of a sphere that has the same height and a circular base with the same diameter.
We know that volume of cone is .
The height is equal to the diameter. We know that diameter is 2 times radius, so we can represent this information in an equation as:
Upon substituting in volume of cone, we will get:
We know that volume of sphere is .
Upon comparing volume of cone with volume of sphere, we can see that volume of sphere is 2 times the volume of cone.
Since , so volume of sphere would be:
Therefore, volume of sphere would be 226.08 cubic mm.
Answer:
Tj should write 5.75 hours on her time card.
Step-by-step explanation:
We have been given, Tj worked for 5 hours and 45 minutes.
We will convert 45 minutes to hours by dividing 45 by 60 as one hour has 60 minutes.
=0.75 hours
Hence, Tj should write 5.75 hours on her time card.
