Answer:
22π=2πr. Divide both sides by 2π so r=11. Area = πr^2=121π.
Step-by-step explanation:
Answer:
Yes, because all regular polygons fit this definition.
Choice D is correct
Step-by-step explanation:
A polygon is said to be regular if it is equiangular that is all its angles are equal and equilateral which implies that all its sides have equal length. Examples of regular polygons include;
Regular pentagon
Regular octagon
Since the figures are similar, we can establish a rule of three as follows.
We know that the area of the smaller figure is
, and its volume is
. We also know that the area of the larger figure is
; since we don't now its volume, lets represent it with
:
We can conclude that the volume of the larger figure is
; therefore, the correct answer is
a.
Hey there! I'm happy to help!
You haven't provided any answer choices but I can show you a trick to find any number between two numbers. This is will give you an instant answer to one being greater than one number and less than another.
What you do is you add the two numbers and divide by two!
2/5+3/5=1
1÷2=1/2
Therefore, 1/2 is a possible answer here.
I hope that this helps! Have a wonderful day!
