Volume of Solids
The volume of the solid is 758.83 in³
Step-by-step explanation:
Given that the cone and half sphere is hollow
The volume of the cone =
The Volume of the sphere = 
So the Volume of the half sphere =
The volume of solid = volume of cone + volume of the half sphere

Given
height h = 19 in
radius r = 5 in
= 
= 1/3 × 3.14 × 5 × 5 × 19
= 497.16 in³

= 2/3 × 3.14 × 5 × 5 × 5
= 261.67 in³
V = 497.16 in³ + 261.67 in³
= 758.83 in³
Hence the volume of the solid is 758.83 in³
Answer: Probability of meeting is 0.67
Step-by-step explanation: Since each person decided to wait for 20minutes thus within an hour a maximum of 40minutes is spent waiting by both parties.Therefore, Probability of meeting will be 40mins/60mins=0.666 approximately 0.67
P = 2(L + W)
P = 56
W = L - 6
56 = 2(L + L - 6)
56 = 2(2L - 6)
56 = 4L - 12
56 + 12 = 4L
68 = 4L
68/4 = L
17 = L <====length (L) = 17 inches
W = L - 6
W = 17 - 6
W = 11 <== width (W) = 11 inches
It’s FALSE if the two lines intersect they intersect at that point only and it’s one solution
False. .02*10 is .2, not 2.
