Answer:
About 28.26 inches.
Step-by-step explanation:
The formula for circumfrence is c = 2(pi) * r.
We know that r = 4.5 (because the diameter is 9 inches).
So, the equation is c = 2(pi) * 4.5
Let's solve:
c = (2*3.14) * 4.5
c = 6.28 * 4.5
c = 28.26
Therefore, the final answer is 28.26 inches.
Of course, this is not exact because pi is irrational and goes on forever, but the question is asking for an estimate anyways.
The formula for area of a square is A = a², where a is the length of one of the sides.
If the side length of this square is 6, the area is 6² or 36 units².
Answer:
A. 36 square units

Part 1:
Plan 1: y = 25x
Plan 2: y = 120 + 10x
x = number of weeks
y = total money
Part 2:
Plan 1 requires 8.8 weeks.
220/25 = 8.8
Plan 2 requires 10 weeks.
220 - 100 = 100
100/10 = 10 weeks
Plan 1 is best since the money is earned faster.
Answer:
312
Step-by-step explanation:
First we need to determine the width
A = l*w
6.2 * 10 ^3 = 1.55 * 10 ^2 * w
Divide each side by 1.55 * 10 ^2
6.2 ^ 10 ^3 /1.55 * 10 ^2 = 1.55 * 10 ^2 * w / 1.55 * 10 ^2
Changing from scientific notation to standard
6200/155 = w
40 = w
Then we need to determine the perimeter
P = 2(l+w)
P = 2( 155+40)
P =2( 195)
P = 390
Now multiply by the price
390 *.80
312
I'm pretty sure this one is super easy
you just take 144 and divide it by 6 which would look like
144/6 then the answer is 24
