Is 4:30 because ,12:45 take away 8:15= 4 :30 and 8 to 12 they are 4 and 45 take way 15 is 30
Answer: 6259.9 cu. cm.
For 6)
Volume, V, for a cylinder:
generally V = A * h = πr^2h, therefore,
V1 = πr1^2h for the volume enclosed by C1
V2 = πr2^2h for the volume enclosed by C2
V = V1 - V2 for the volume of the solid, the tube.
V = π(r1^2 - r2^2)h
12 x 2 = 24
When you multiply two negative numbers, the answer will be a positive
When you multiply one negative and one positive, the answer will be negative.
Using that rule:
(-12)(-2) = 24
24 is your answer
hope this helps
Answer:
a) (3, -4), (2, 4), (-5, -6)
b) (4, 3), (-4, 2), (6, -5)
Step-by-step explanation:
a) Reflection in the x-axis negates the y-coordinate:
(x, y) ⇒ (x, -y)
(3, 4) ⇒ (3, -4)
(2, -4) ⇒ (2, 4)
(-5, 6) ⇒ (-5, -6)
__
b) Reflection in the line y=x swaps the x- and y-coordinates:
(x, y) ⇒ (y, x)
(3, 4) ⇒ (4, 3)
(2, -4) ⇒ (-4, 2)
(-5, 6) ⇒ (6, -5)
