Answer:
43.96 inches
Step-by-step explanation:
(refer to attached)
circumference = 2πr, where r = 7 inches and π=3.14
circumference = 2 x 3.14 x 7
= 43.96 inches
Answer:
C, Plus or minus 3
Step-by-step explanation:
to solve 3x² - 27 = 0, we want to get the x by itself, so lets add 27 to both sides.
3x² = 27 < divide both sides by 3 to get x alone
3x²/2 =x²
27/3 = 9
x² = 9 < we can use the square-root property and square both sides of the equation to get x alone. we use the ± because there are 2 possible solutions to a square rooted number
√x² = x
√9 = 3
x = ±3
looking at our answer choices, the correct answer is C
Answer:
a
Step-by-step explanation:
multiply the radius of 3 by 3 to get 9, and multiply the height of 4 to get 12. the radius of cylinder a = 9 and the height of a = 12 therefore if you fill cylinder b up 3 times you will fill up a.
