Mr. James has cylindrical beakers that measure 4 inches in diameter and 9 inches high. What is the volume contained within the b
eakers? Use 3.14 for pi. Round your answer to the nearest hundredth.
1 answer:
So 4 inches diameter result the radius is 4/2 = 2 inches
area of base = pir^2 = 3,14*2^2 = 3,14*4 = 12,56 inches squared
volume = area of base *height
V = 12,56 *9 = 113,04 so rounded 113,05 inches cubed
hope this will help you

The unknown number is 69.
*If you reverse 69, it would be 96. Thus, increasing its value by 27.
96 - 69 = 27
*The sum of its digits 6 and 9 equals to 15.

Answer:
-10n - 60
Step-by-step explanation:
Use the distributive property to simplify [ a(b + c) = ab + ac ]
-10(n + 6)
(-10 * n) + (-10 * 6)
-10n + -60
-10n - 60
Best of Luck!
3h - 27 = 36
3h = 63
h = 21
