Answer:
Step-by-step explanation:
(a) radius is the bottom leg of the right triangle formed by the slopped edge and the vertical line from the tip to the center of the base. So that's easy enough with the pythagorean theorem.
15^2 + b^2 = 34^2
b = sqrt(1156 - 225)
b = 30.512
(b) The surface area can be looked at as the surface area of the circular base + the surface area of the actual cone.
area of a circle is pi*r^2 and the surface area of the cone, excluding the base, is pi*r*s, where s is the slant height. If you want to know where that one comes from it kinda takes some calculus to understand but I can link a video to explain it.
pi*r^2 + pi*r*s
pi(r^2+rs) I factored out pi to make things a little easier.
pi(931+30.512*34)
1968.408pi Feel free to multiply out pi.
(c) Volume for a cone (or any kind of pyramid) is area of the base times the height all divided by 3.
so since we know the area of the base we can just plug in.
(pi*r^2*h)/3
(pi*931*15)/3
4655pi
Answer:
The correct option for this is C.) The mean and median age are more likely to be the same for the students in Math 1.
Step-by-step explanation:
i) The median age of the students is Math 1 is less than the median age of the students in Math 2.
This statement is NOT TRUE as the median age of students in Math 1 = median age of students in Math 2 = 19
ii) The mean and median age are most likely the same for both sets of data.
This statement is NOT TRUE. The mean age of students in Math 2 should be greater than mean age of students in Math 1.
iii) The mean and median age are more likely to be the same for the students in Math 1.
This statement is TRUE.
The common solution by graphing will be.. x=1
