Answer:
The circumference is 98.39 centimeters (rounded to 2 decimal places)
Step-by-step explanation:
The area of a circle has the formula 
The circumference of a circle has the formula 
First, let's find r from area given:
Now, we can use this value of r and plug in into the formula for circumference. Shown below:
The circumference is 98.39 centimeters (rounded to 2 decimal places)
Hi! I'm happy to help!
To solve for this, we need to understand what a ratio is. A ratio is a comparison between two things. (in numbers) In this case, between pools and hours:
pools:hours
A fraction is also a ratio, in this case we have 2/5, which also compares pools to hours, so we can turn this into a more proper ratio form:
2 pools: 5 hours
2:5
<u>So, our ratio of pools to hours is 2:5.</u>
I hope this was helpful, keep learning! :D
The median is the middle value in a list ordered from smallest to largest.
Answer:
Part A: A(m(t)) = π(81t²); Part B: 1017.36
Step by step explanation:
Part A:
To find A(m(t)), we substitute our value for m(t), 9t, in place of m:
A(m(t)) = πm² = π(9t)² = π(81t²)
A(m(t)) = π(81t²)
Part B:
Substitute 2 in for t:
A(m(2)) = π(81(2²)) = π(81(4)) = 3.14(324) = 1017.36
Answer:
2x - 6y
Step-by-step explanation:
Combine like terms
(x) - 7y + (x) + y
2x - 7y + y
Combine like terms again
2x - (7y) + (y)
2x - 6y
Hope this helps!
