Question: A circular garden has a diameter of 10 m. What is its area? (Use π = 3.14)

Options:

Correct Answer: 78.5 m²

Solution:

Radius = diameter/2 = 10 m/2 = 5 m. Area = πr² = 3.14 × (5 m)² = 78.5 m².

A circular garden has a diameter of 10 m. What is its area? (Use π = 3.14)

Correct Answer: 78.5 m²

Step 1: Identify the diameter of the circular garden, which is given as 10 meters.
Step 2: Calculate the radius by dividing the diameter by 2. So, radius = 10 m / 2 = 5 m.
Step 3: Use the formula for the area of a circle, which is Area = πr².
Step 4: Substitute the value of π (3.14) and the radius (5 m) into the formula. So, Area = 3.14 × (5 m)².
Step 5: Calculate (5 m)², which is 25 m².
Step 6: Multiply 3.14 by 25 m² to find the area. So, Area = 3.14 × 25 = 78.5 m².
