I think the answer is A.
the formula to find the volume of a sphere is 4/3 x pi x radius cubed. this means you have to split the diameter in half giving you 3.7 which automatically rules out the answers with 7.4 written in them. now you have to compare A and D but D has 3/3 at the end. this is where you can see that it’s wrong because when you cube you don’t use a fraction.
1 should be 21 because u have to add m(1)+112+57 and get 180°,,,, angle 2 should be 33 because there is a right angle (90°) and when u add 90+57=147 u gotta substract it from 180 and u get 33,,, angle 3 is 71 because there is another right angle (90°) and when u add 19 and 90 it’s 109 and substract from 180 and u get 71
