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

Options:

Correct Answer: 154

Solution:

Area = πr² = (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 in square meters? (Use π = 22/7)

Step 1: Identify the formula for the area of a circle, which is Area = πr².
Step 2: Substitute the value of π with 22/7 and the radius (r) with 7 meters into the formula.
Step 3: Calculate r² (7 squared), which is 7 × 7 = 49.
Step 4: Multiply π (22/7) by r² (49). This means (22/7) × 49.
Step 5: Simplify the multiplication. The 7 in the denominator cancels with the 49, leaving 22 × 7.
Step 6: Calculate 22 × 7, which equals 154.
Step 7: Conclude that the area of the park is 154 square meters.

Area of a Circle – The area of a circle is calculated using the formula A = πr², where r is the radius.
