Answer explanation

ALWAYS ADD A LABEL

When looking for the area, what should we do if the diameter is given instead of the radius?

• Multiply π and the diameter

• Divide the diameter by two so we can have "A= π x r x r"

• Multiply the diameter by two so we can have "A= π x r x r"

• Divide the diameter with π

If the diameter is 20, what is the area?

• 123.07cm^2
