<h3>Answer: Tony is correct</h3>
========================================================
Explanation:
There are number of ways to go about this, but let's pick on the sides marked in the diagram below (circled in red and blue). I picked on those sides specifically because they are on either side of the marked angles (A and Q).
They help form the proportion below, in which we'll show later on its a false statement.
AE/PQ = AB/QR
24/(14.5) = 18/(11.5)
24*11.5 = 14.5*18
270 = 261
We arrive at a false statement at the end, so the original proportion is false. Furthermore, it means the figures are <u>not</u> similar.
--------------
We could try the other way around and try to see if
AE/QR = AB/PQ
is true or not
Let's find out
24/(11.5) = 18/(14.5)
24*14.5 = 11.5*18
348 = 207
We see this is false as well. The gap is even bigger than before, so the first scenario was slightly close to having similar polygons. But neither case works perfectly. So that's why we don't have similar polygons and why Tony is correct. It's not enough to look at the angles only when dealing with polygons that have more than 3 sides. If we were just focused on triangles, then Jacenta would be correct.
Answer:
around 33.51
Step-by-step explanation:
Hello! :)
Let’s start with the basics:
<u><em>How to Find the Volume of a Sphere:</em></u>
Formula: V= 4/3r^3, which means the volume is 4/3 times the approximation of pi (3.14 or 22/7) time the radius with an exponent of 3.
Now that we know how to find the volume of a sphere, let’s solve the actual problem :D
The diameter is 4. We have to find the radius to find a volume of a sphere.
The radius is the diameter divided by 2; <u>that makes our radius, 2.</u>
So, V= 4/3(2)^3
Let’s solve the exponent first. 2^3= 2(2)(2) which is 8.
Now, you can either solve 4/3 times 8 first, or 4/3 times pi. I’m going to solve 4/3 times 8 to make it a little bit easier.
4/3 times 8= 32/3 which is around 10.7 (10.6667).
Now, let’s do 10.7 times pi. (I’ll be using 3.14 as the approximation of pi.)
10.7 x 3.14= 33.598 (actual answer using 10.6667 is 33.51).
And there you go! I hope this helps, let me know if you have any questions/I did anything wrong. Good luck! :D
