I think the answer you are looking for is 28.
7/8 multiplied by 32 gives you 28.
You would just plug the values into the slope-intercept formula which is y=mx+b. m is representative of the slope, and b is representative of the y-intercept. The equation would be y=-9x+5
The answer should be A and D
Volume of the sphere is 4/3*pi*r^3
here, r is 11 yd.
volume = 4/3*pi*11^3
= 4/3*pi*1331
= 5575.28 yd^3
= 5575.3 yd^3
