Answer:

<h2>132.25π  m²</h2>

Step-by-step explanation:

The circumference of a circle is 23π

On the other hand, The circumference of a circle = 2×π×r ; where r is the radius.

then

by equating the last two expressions we get: 23π = 2πr then r = 23/2

then

the area = π × r² = (23/2)²×π = (132.25)×π

What's happening is that every subtraction can be written as "addition of the opposite."

18-5 = 18 + (-5)

One reason this is done in the work you showed is that they're trying to show why you distribute the negative and the 1 into the parentheses, why you multiply everything in the parentheses by "-1" and not just 1.

The other reason is to later to be able to move the individual terms around, so you'll be able to combine like terms.

When you move terms around, the sign has to stay attached to the term, so writing all the subtractions as addition helps keep the sign attached.

Find the area and the circumference of the circle. Round your answers to the nearest hundredth. PLEASE SHOW WORK
larisa [96]

27/2=13.5(radius)

area: pi*r*r=

pi*13.5*13.5=

572.55526

rounded, 572.56

circumference: 2*pi*r(which is basically diameter times pi)

27pi=84.823

rounded, 84.82

Erika calculated that she would spend $115 on school supplies this year. She actually spent $82.50 on school supplies. What is E
DerKrebs [107]
The equation to find percent error is:
percent error=(experimental-theoretical)/theoretical *100
So, (115-82.5)/82.5=0.393939*100
39.3939%, or 39.94%

Hope this helps!!

Estimate the value of √2
marusya05 [52]

Answer:

B. 0.50

Step-by-step explanation:

It claims to estimate. Square root of 2 would be somewhere around 1. Square root of 5 would be somewhere around 2. Then you divide, 1/2, and that should equal 0.50.

I hope this is correct!
