- Hi so it's ask for area of circle an you know that formula for area of circle is πr2 r (radius)
- What is π? We have two formula π which is 22/7 or 3.142.So for this question i will use 22/7.
- If you look at question 2,4 and 6 you can see the diameter which line straight to the circumference. That's call diameter. But in the formula it want r which mean radius. So the diameter÷2

Answer:
Given sides 12, 16 and 20 can be the sides of right triangle.
Step-by-step explanation:
Sides of right triangle always follow the Pythagoras theorem.
i.e
For the given Lengths 7, 40 and 41
We need to check if
That means,
hence 7,40 and 41 can not be the sides of right triangle.
Next,
Given sides 12,16 and 20.
Again follow the similar process used in the above problem.
Therefore given sides 12,16 and 20 can be the sides of right triangle.
