Answer:
50.27 (to 2dp)
Step-by-step explanation:
radius = 4
area of circle = pi * r * r
16 pi is area = 50.2655 units^2 (to 4dp)
You first have to find the length of each side.
AB=4
BC=4
CD=4
AD=4
Since this is a quadrilateral, two sides will have the same length, in this case, they all do so you can pick any two sides.
4(4)=16.
-- Start with zero.
then
-- Subtract 1 from the number you have now.
-- Do this as many times as you feel like, until you get bored.
-- Every time you do it, the result is a different correct answer to this question.
Here are 3 examples:
-1
-2
-10 million
There are an infinite number of others.
Answer: I believe the answer is (2) 49
Explanation: The given ratio is 5:245
When simplified(245/5), it gives you 1:49!
the area of the surface of this design is 31 in long
