The large sphere has a diameter of 20 feet.
Which expression represents the volume, in cubic units,
of the shaded part of the sphere?
04(109) + 47(49)
-A(109) - 37(43)
o A(209) + 47(43)
or(209) - 4r(43)

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
