To calculate the Volume of a sphere we use =

i
in this question our radius is 6cm and height is 30cm therefore the volume will be :-
(1/3)\pi *(6)^{2}*30
Answer= 360 cm^{3}
First combine like terms in parentheses. 4x-5x = -1x. Now -1x - 5y should be in the parentheses. Now use the distributive property and multiply both of those terms by 2. The product is -2x -10y so the answer is B.
Answer:
Jayln rode 12.4 miles/hour.
Step-by-step explanation:
The question is asking for a unit rate for the speed in miles per hour that Jayln rode her bike over her 33.48 mile ride. Since we know that she rode a total of 33.48 miles and the total time was 2.7 hours, we can set up our ratio as 33.48/2.7 or miles/hours. In order to find unit rate, or the number of miles per one hour, we need to divide: 33.48 ÷ 2.7 = 12.4. So, 12.4 mph is Jaylyn's speed.
