Question: A circular park has a radius of 7 meters. What is the area of the park? (Use π = 22/7)

Options:

Correct Answer: 154

Solution:

Area = π × radius² = (22/7) × 7² = (22/7) × 49 = 154 square meters.

A circular park has a radius of 7 meters. What is the area of the park? (Use π = 22/7)

A circular park has a radius of 7 meters. What is the area of the park? (Use π = 22/7)

Step 1: Identify the formula for the area of a circle, which is Area = π × radius².
Step 2: Substitute the value of π with 22/7 and the radius with 7 meters into the formula.
Step 3: Calculate the square of the radius: 7² = 49.
Step 4: Multiply π (22/7) by the squared radius (49): (22/7) × 49.
Step 5: Simplify the multiplication: (22 × 49) / 7.
Step 6: Calculate 22 × 49 = 1078.
Step 7: Divide 1078 by 7 to get the area: 1078 / 7 = 154.
Step 8: State the final answer: The area of the park is 154 square meters.

Area of a Circle – The area of a circle is calculated using the formula A = π × r², where r is the radius.
