Which of the following formulas could be used to calculate the combined area,x of threw identical circles?
A. X= 3pie r squared
B. X= 6 pie r
C. X= pie r squared/ 3
D. X= 6 r/ pie
Do you mean pi (not pie)?
Do you mean three (not threw)?
Yes, sorry about that.
The formula for the area of a circle is
A = pi * r^2
Which of your choices shows the formula for the areas of three identical circles?
I'll be glad to check your answer.
A= 3pi r squared?
Right! :-)
mrs, smith baked 4 pies.she cut each pie in to 8 equal pieces. if 5 of pie were eaten,what fraction of the pies is left?
To calculate the combined area of three identical circles, you need to know the formula for finding the area of a single circle and then multiply it by 3.
The formula for finding the area of a circle is A = πr^2, where A is the area and r is the radius of the circle.
Let's go through each of the given formulas and determine if it matches the correct formula.
A. X = 3πr^2: This formula states that the combined area is equal to 3 times π times the square of the radius. This matches the correct formula for finding the area of a single circle, so option A is correct.
B. X = 6πr: This formula states that the combined area is equal to 6 times π times the radius. This does not match the correct formula for finding the area of a circle, so option B is not correct.
C. X = πr^2/3: This formula states that the combined area is equal to π times the square of the radius, divided by 3. This is not the correct formula for finding the area of a circle, so option C is not correct.
D. X = 6r/π: This formula states that the combined area is equal to 6 times the radius, divided by π. This is not the correct formula for finding the area of a circle, so option D is not correct.
Therefore, the correct formula to calculate the combined area, x, of three identical circles is option A: X = 3πr^2.
