Question
A circular hockey puck has a diameter of 6 cm. Determine the area of one side of the hockey puck to the nearest tenth of a square centimetre (do not include the unit with your answer).
Solution
To find the area of a circle, you use the formula A = πr², where r is the radius of the circle.
Step 1: The diameter of the hockey puck is given as 6 cm. The radius is half of the diameter, so the radius of the hockey puck is 6 cm / 2 = 3 cm.
Step 2: Substitute the radius into the formula for the area of a circle. A = π(3 cm)² = π(9 cm²) = 28.3 cm².
So, the area of one side of the hockey puck is approximately 28.3 square centimeters.
