Consider two nonparallel planes X, Y that go through to the center of a sphere of radius one. This cuts the sphere into 4 parts A, B,C, D. The two parts A, B are on the same side of X, such that the volume of A is greater than the volume of B. If the expected value of the volume of A can be expressed as ab⋅π, where gcd(a, b)=1 find a+b. Thank you!

Vikram is studying the square pyramid below. on st to find the surface area of the pyramid, in square inches, vikram wrote (33.2) (34 ikram wrote (33.2)(34.2)+43(34.2)(284) what error did vikram make? o he used the same expression for the area of all four lateral faces. he used the wrong expression to represent the area of the base of the pyramid. o he used the wrong value as the height when he found the area of the lateral faces. he used an expression for surface area that only finds the total area of three faces.
