Answer:
a) 235.62in³
b) 904.78in³
Step-by-step explanation:
a) The formula to find the volume of a cylinder is:
We are given that r = 5 and h = 3, so we can just plug in and solve:
b) The formula to find the volume of a sphere is:
We are given that the diameter is 12in, which means that the radius (r) must be 6in (half the diameter). Now, we can plug in and solve:
X1=0
Y1=-3
X2=4
Y2=1
Slop=(y2-y1)/(x2-x1)
Slop=(1-(-3))/(4-0)
Slop=4/4
Slop=1
