If the area of a circle is 28.26 cm2 , what is the radius of the circle?(1
The formula for the area of a circle is A = πr², where A is the area and r is the radius.
Given that the area of the circle is 28.26 cm², we can plug this value into the formula and solve for the radius:
28.26 = πr²
To solve for r, we first need to divide both sides of the equation by π:
28.26/π = r²
r² = 9
r = √9
r = 3
Therefore, the radius of the circle is 3 cm.
