Answer:
28.26 cm^2
Step-by-step explanation:
The formula to calculate the area of a circle is a=πr²
where π (pi) is a constant with a value of 3.14 or 22/7 and r=radius. Take note that the formula use radius, which equals to 1/2 of diameter. The radius of a circle with 6cm diameter will be:
r= 1/2 * d
r= 1/2 * 6cm
r= 3cm
Then the calculation for the area is:
a=πr²
a=3.14 * (3cm)²
a= 3.14 * 9cm²
a= 28.26 cm²
