The area of a circle (A) is given by the formula A= pi*r to the second power, where r is the radius. The formula to find r is _.
podryga [215]

Answer:

<u>The correct option for the first blank is A. (A/pi) to the power of 1/2</u>

<u>The correct option for the second blank is A. 4.15</u>

Step-by-step explanation:

1. Let's review the information provided to us to answer the questions correctly:

Area of a circle (A) = π * r², where r = radius

2. The formula to find r is ________________:

A = π * r²

r² = A/π

√r² = √ A/π

r =  √A/π

<u>r =  A/π∧(1/2) or  (A/pi) to the power of 1/2. </u>

<u>The correct option for the first blank is A. (A/pi) to the power of 1/2</u>

3. if A = 54 centimeters squared, and pi = 22/7, r is _ centimeters.

We use the formula we got for the first blank, this way:

r =  (A/pi) to the power of 1/2

Replacing with the real values, we have:

r = (54/(22/7)) to the power of 1/2

r = 17.2 to the power of 1/2

r = √17.2 = 4.15 (Rounding to the next hundredth)

<u>The correct option for the second blank is A. 4.15</u>
