If you have a circle with an area of approximately 45 square feet, what is a good estimation for the radius of the circle?(4 points)
Step 1: What is the formula for finding the area of a circle? Response area
Step 2: What would be the first step in solving for the radius? Response area
Step 3: What would be the second step in solving for the radius? Response area
Step 4: The approximate radius would be about
answers
2.1 feet
205 feet
take the square root of each side of the equation
multiply by 2 on each side of the equation
divide by pi on each side of the equation
subtract pi from each side of the equation
7.16 feet
3.8 feet
divide by 2 on each side of the equation
A = pi r ^2
C = 2 pi r ^3
multiply by pi on each side of the equation
A = 2 pi r ^3
square each side of the equation
Step 1: The formula for finding the area of a circle is A = pi r^2.
Step 2: The first step in solving for the radius would involve rearranging the formula to solve for r. So, r = sqrt(A / pi).
Step 3: The second step would be to substitute the area value of 45 square feet into the formula. So, r = sqrt(45 / pi).
Step 4: The approximate radius would be about 3.8 feet.
for step 2 and 3 i do not see those answers
Apologies for the confusion. Here are the correct responses for steps 2 and 3:
Step 2: The first step in solving for the radius would involve rearranging the formula to solve for r. So, r = sqrt(A / pi).
Step 3: The second step would be to substitute the area value of 45 square feet into the formula. So, r = sqrt(45 / pi).
I hope this clears things up. Thank you for pointing that out.
for step 2 and 3 what do i put use the answers i provided
My apologies for the oversight. Let's correct that:
Step 2: The first step in solving for the radius would be r = sqrt(45 / pi).
Step 3: The second step would be to calculate the square root of 45 divided by pi.
Using the provided answers, the approximate radius would be about 3.8 feet.
Step 2: What would be the first step in solving for the radius? Response area
use the answer i provided
Step 2: The first step in solving for the radius would be to divide by pi on each side of the equation. So, r = sqrt(45 / pi).
If we use the provided answers, the approximate radius would be about 3.8 feet.
