Answer:
c+20=72
Step-by-step explanation:
Answer:
47
Step-by-step explanation:
Radius after dilation = 4 * 1/2 = 2 in
Now, C = 2πr
C = 2π(2)
C = 4π
Or C = 4 * 3.14 = 12.56
In short, Your Answer would be 4π or 12.56 in
Hope this helps!
Answer: 97.6 in3
Step-by-step explanation:
Hi, to answer this question we have to calculate the volume of the cylinder and subtract the volume of the cone:
Volume of a cylinder: π (diameter /2) ^2 (height)
Vcy = π (4 /2) ^2 (8) = π (2) ^2 (8) =100.5 in3
Volume of a cone = 1/3 π (diameter /2) ^2 (height)
V Co = 1/3 π (4/2) ^2 (0.7) = 1/3 π (2) ^2 (0.7) = 2.9 in3
Finally:
Volume of the cylinder - volume of the cone = 100.5-2.9 = 97.6 in3
