A tent has a conical roof and cylindrical wall as shown. The cylindrical wall and conical roof are of the same height. The radius of the tent is 9 meters. Ropes are used to tie the tend to the ground. A) find the height of the wall. B) Find the volume of space inside the tent.

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
