<h2>
Diameter of a Circle</h2>
There are multiple strategies we can use to find the diameter of a circle. For this question, we must calculate the length of the radius first and multiply by 2 to find the diameter.
<h2>Solving the Question</h2>
We're given the centre and a point on the circumference:
.
Find the distance between them using the distance equation:

Plug in the given points:

Therefore, the radius of the circle is 10 units.
Multiply the radius by 2 to find the length of the diameter:
10 × 2
= 20
Therefore, the length of the diameter is 20 units.
<h2>Answer</h2>
20 units

Step-by-step explanation:


Answer:
A) about 1 pet
Step-by-step explanation:
Total the products of number of pets and their probability.
... 0×0.4 +1×0.3 +2×0.25 +3×0.05
... = 0 +0.3 +0.5 +0.15 = 0.95 . . . . . about 1
___
We assume that "3 or more" will be closer to 3 than to 15, a number that would raise the expected value to more than 1.5.
Answer:
The number of ways is equal to 
Step-by-step explanation:
The multiplication principle states that If a first experiment can happen in n1 ways, then a second experiment can happen in n2 ways ... and finally a i-experiment can happen in ni ways therefore the total ways in which the whole experiment can occur are
n1 x n2 x ... x ni
Also, given n-elements in which we want to put them in a row, the total ways to do this are n! that is n-factorial.
For example : We want to put 4 different objects in a row.
The total ways to do this are
ways.
Using the multiplication principle and the n-factorial number :
The number of ways to put all 40 in a row for a picture, with all 12 sophomores on the left,all 8 juniors in the middle, and all 20 seniors on the right are : The total ways to put all 12 sophomores in a row multiply by the ways to put the 8 juniors in a row and finally multiply by the total ways to put all 20 senior in a row ⇒ 
Answer:
Volume of cone = 40 in³
Step-by-step explanation:
Given:
Volume of cylinder = 120 in³
Height of cylinder = Height of cone
Radius of cylinder = Radius of cone
Find:
Volume of cone
Computation:
Volume of cylinder = πr²h = 120 in³
Volume of cone = (1/3)πr²h
So,
Volume of cone = (1/3)(120)
Volume of cone = 40 in³
