ANSWER = 17.5% of 360 = 63
EXPLANATION:
Find 10% of 360 = 36
Then 5% of 360 = 18
Then 2.5% of 360 = 9
Add them together
so 17.5% of 360 = 63
Sam measures the height of 7 different scoops of ice cream. The mean height was 3.8 cm. If all the scoops are evenly distributed, they would all be 3.8 cm tall.
<h3>How to find the mean value of a data set?</h3>
The mean value of the data set is the ratio of the sum of the data set's values to the number of values it has.
If the data set consists of values
x_1, x_2, ..., x_n
, then we get the mean value as:
![\overline{x} = \dfrac{x_1 + x_2 + \cdots + x_n}{n}](https://tex.z-dn.net/?f=%5Coverline%7Bx%7D%20%3D%20%5Cdfrac%7Bx_1%20%2B%20x_2%20%2B%20%5Ccdots%20%2B%20x_n%7D%7Bn%7D)

Therefore, If all the scoops are evenly distributed, they would all be 3.8 cm tall.

Answer A: 84π
Answer B: I'm also confused. If anyone else knows can you please help me also. Sorry for not answering B. I hope this helps though.
Step-by-step explanation:
Answer A:
V=1/3π 6^2 (7) Since 12 is a diameter you half it which is 6
V=1/3π 36(7)
V=1/3π 252
V= 252π/3
V=84π
