Answer:
Step-by-step explanation:
A) either radius or diameter and height
V = πR²h or πD²h/4
B) Radius is half a diameter, R = 4 cm
C) Rather depends on how they are put together.
Placing the rectangular faces touching would make a cylinder
D) V = 3.14(4²)(2) = 100.48 ≈ 100 cm³
E) divide by 2
i.e. V = ½πR²h
F V = ½(3.14)(4²)(2) = 50.24 ≈ 50 cm³
Answer:
Step-by-step explanation:
hello!
(l*L *h)/3 =
(4*11* 9)/3 => 132 km³
Answer:
Migration is D, the seasonal movement of organisms between locations!
Answer:
The other endpoint of the segment is 
.
Step-by-step explanation:
The midpoint of the points 
and 
is given by the following formula:
where 
= coordinates of the midpoint.
We know that the midpoint is (-15, 2) and an endpoint is (-12, 11). Substituting the information we have gives:
To find 
we need to solve this equation:
and to find 
we need to solve this equation:
The other endpoint of the segment is 
.
The answers are:
P(9, 2) = 72
P(5, 5) = 120
P(7, 7) = 5040
These are examples of permutations. The problems are asking us to find the total number of ways an event can happen.
In the first case, P(9, 2), we are asked to find the ways that 2 things can be chosen out of a group of 9.
9 x 8 = 72
P(5, 5) = 5 x 4 x 3 x 2 x 1
P(7, 7) = 7 x 6 x 5 x 4 x 3 x 2 x 1
