1st problem:
Use the Pythagorean theorem:
a^2+b^2=c^2
49+361=c^2
c^2=410
c=20.24
The answer is 20m
2nd problem:
First calculate the height using the Pythagorean theorem:
a^2+b^2=c^2
20^2+b^2=625 (i got 20 {radius} by half-ing the base edge length)
400+b^2=625
b^2=225
b=15
Next, solve for the volume:
V=a^2*h/3
V=40^2*15/3
V=1600*5
V=8000
The answer is the second choice or B.
i believe the answer is 35 dimes and 65 nickels (sorry if i’m wrong lol)
Answer:
Step-by-step explanation:
Here we are given four equations and we have to find the equation that gives the number of half inches that are in 
inches.
To find how many half inches i.e. 
inches are there in inches we have to divide by .
So, the equation that will give the result is 
(Answer)
In a fraction, the fraction bar means divided by. So to find the decimal form equivalent of a fraction like 1/4 you need to solve the math problem 1 dived by 4.
1 ÷ 4= 0.25
