Hi all. Please assist me with calculations for the problems I have. For a sphere with a diameter of 45.7cm and height of 23.8cm calculate the surface area and volume, show workings for both calculations. Cube with a diameter of 15cm and height of 20cm and a cylinder with a diameter of 10cm and height of 12cm. Please do show the formulas used for all the calculations and all the workings. Thank you

For a sphere with a diameter of 45.7cm and height of 23.8cm calculate the surface area and volume, show workings for both calculations.

Doing the actual work is kinda your job. :shock:

What do you mean by the "height" of the sphere? What formulas did they give you for the volume V and the surface area SA for a sphere with radius r (or diameter d = 2r)? How far have you gotten in plugging the given values into the given formulas?

Cube with a diameter of 15cm and height of 20cm and a cylinder with a diameter of 10cm and height of 12cm.

What are you supposed to do with these? What is meant by the "diameter" of a cube? How far have you gotten in plugging the given values into the formulas they gave you?

Please be complete. Thank you!
