<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
Answer:
I noticed it has already been 2 minutes do you still need help with the equation? also do you know the tittle of the problem? what category in mathematics?
Step-by-step explanation:
Answer:
480 Litres
Step-by-step explanation:
Percentage increase = 20% × 400
New value =
400 + Percentage increase =
400 + (20% × 400) =
400 + 20% × 400 =
(1 + 20%) × 400 =
(100% + 20%) × 400 =
120% × 400 =
120 ÷ 100 × 400 =
120 × 400 ÷ 100 =
48,000 ÷ 100 =
480

Answer:
k = g(x)/f(x)
Step-by-step explanation:
Unless there is more to the question, the answer is g(x) / f(x) = k
You just need to divide both sides by f(x)
Here's an example
f(x) = 20x + 40
g(x) = 80x + 160
k = g(x)/f(x) = (80x + 160) / (20x + 40) = 4*(20x + 40)/(20x + 40)
k = 4
