Answer:

Step-by-step explanation:

The area of a circle is expressed as

Area = πr^2

Where r = radius of the circle

π = constant = 3.14

The radius of a circle is increased from 8.00800 to 8.03803 m. This means that the original radius of the circle is 8.00800 and the new radius of the circle is 8.03803

Area of original circle =

3.14 × 8.00800^2 = 201.36212096

Area of new circle =

3.14 × 8.03803^2 = 202.87516852203

Increase in area = 202.87516852203 - 201.36212096

= 1.51304756203

Expressing the change as a percentage, it becomes

1.51304756203/201.36212096 ×100

Percentage change = 0.75 %

Toillet paper is sold in cases for 36 rolls for $14.99 what is the per price per roll?
Eva8 [605]
Alright, so the unknown value here we want to know is the price of one roll of TP. Let's call it "x".
36x=14.99
Divide both sides by 36 to get the price of a single roll.
x=.41638888....
We have to round this to hundredths because we're talking in cents, so...
x=.42
Each roll of toilet paper costs 42 cents.

The area of a square is 15.1 units². Estimate the length of the sides. Explain how you estimated.
kykrilka [37]

If it is just an estimate then it would be around <em>4</em>. 15.1 is pretty close to 16 which has a perfect square root of 4. Since it is a square both length and width would be the same. To check it you can just square 4 or 4 times 4 and get 16. Hopefully I helped! And sorry if I am wrong.

BTW the exact answer would be 3.88~ (square root of 15.1) just incase you needed that. :)

In a circle, the circumference and diameter vary directly. Which of the following equations would allow you to find the diameter
Sergeeva-Olga [200]
The answer is <span>B.154/d = 44/14 
</span>
<span>In a circle, the circumference (C) and diameter (D) vary directly:
C = kD
k = C/D

Circle 1: k = C1/D1
Circle 2: k = C2/D2</span>

C1/D1 = C2/D2
C1 = 154
D1 = ?
C2 = 44
D2 = 14

154/D1 = 44/14
So, the choice B. is correct.
