Ol maths problem

I know i already posted earlier but my e-xamit still won't load!

I'm really stuck on the following questions:

The other half of the metal (2355) was recast as a sphere.
This sphere had a surface area of 272.57(PIE) cm(SQUARED)
Find in cm the radius of the sphere correct to 2 decimal places.


How do you calculate the surface area of a block of wood?


The cylinder in a trophy has a diameter of 8 cm and its volume is four times the volume of the sphere (36 pie) Find h, the height of the cylinder in the trophy


Find the total height of the trophy using the information: A sphere is mounted on a cylinder the radius of the sphere is 3 cm. The volume in terms of pie is 36.

i would be honestly so grateful if anyone can help with anything I'm so frustrated that e-xamit won't load!

What year and paper is this?
Go to examinations.ie and go to material archive and go to marking schemes with your year + level

I have the answer to the first bit!

Surface area of a block of wood is the following

length x height x 2
Height x width x2
Length x width x 2
