Hi, there.
For this question, we can apply the Pythagorean theorem .
I'm sure you've seen this equation before, and they kind of tried to trip you up with this problem. Trust me, it's easier than it looks. Let's break it down.
Lengths a and b both have the value of 48, which means that the value s in is 48, because the length of the hypotenuse is the same as the length and height squared multiplied by 2.
Plug in the value for c:
Plug in the value for s:
Do the innermost exponents first:
The square root symbol and the power of 2 cancel each other out, so we are left with:
s = , so the hypotenuse is 4608 inches.
To find the circumference, multiply the radius by 2, then multiply by PI.
4 3/4 x 2 = 9 1/2
9 1/2 x PI = 9 1/2 x 3.14 = 29.83
Rounded to the nearest inch = 30 inches.
Answer:
D.
Step-by-step explanation:
A=2πrh+2πr2 is the equation, so now all you have to do is plug the numbers in. (also there's a calculator for this on google btw)
I lost my calculator so i can't really help with that but
this is the another way if you can put with multipication
5 x 10³
Answer: $3,980
Step-by-step explanation:
As the question is asking for the amount that Genesis earned over the amount earned by David, to find the answer, subtract David's earnings from that of David.
= Genesis's earnings - David's earnings
= 72,832 - 68,852
= $3,980
