Find the volume of a right circular cone that has a height of 6.7 in and a base with a circumference of 9.8 in. Round your answe
1 answer:
when rounded the answer would be 20cu. inches
The formula for finding the volume of a cone is
1/3(hπr^2)
since we don't know the radius we can find it out through the equation of finding the circumference which is π x d =9.8inches
so the diameter is 9.8/π
which is 3.119437 inches
since the diameter is 2xradius so it would be
3.119437/2=1.559718
so now we can plug this into our equation
1/3(6.7x3.141592653x1.559718^2)
so that would be 17.06851cu.inches

Question:
Below are 36 sorted ages of an acting award winner. find the percentile corresponding to age 38 using the method presented in the textbook. 18 19 20 20 21 23 25 31 33 34 35 37 38 47 50 51 55 55 58 59 62 62 64 66 69 70 70 70 71 71 72 74 74 75 77 80 percentile of value 38 = ______ (round to the nearest integer as needed.)
Answer:
33 percentile
Step-by-step explanation:
Given the ages:
18, 19, 20, 20, 21, 23, 25, 31, 33, 34, 35, 37, 38, 47, 50, 51, 55, 55, 58, 59, 62, 62, 64, 66, 69, 70, 70, 70, 71, 71, 72, 74, 74, 75, 77, 80.
We are told to find the percentile corresponding to age 38.
To find the percentile corresponding to age 38 simply means to find the percentage of ages that are less than 38.
From the given values, the number of ages less than 38 are 12. Therefore, the percentile corresponding to age 38 would be:
(Ages less than 38/ total number of ages) * 100
33.333 ≈ 33
The percentile corresponding to age 38 = 33 percentile
