Question
The radius of a semicircle is 4 meters. What is the semicircle's area?r=4 mUse 𝜋 ≈ 3.14 and round your answe
Solution
The area of a semicircle is calculated using the formula: Area = 1/2 * π * r²
Given that the radius (r) is 4 meters, we can substitute this into the formula:
Area = 1/2 * π * (4 m)²
This simplifies to:
Area = 1/2 * π * 16 m²
Using the approximation of π as 3.14, the equation becomes:
Area = 1/2 * 3.14 * 16 m²
This simplifies to:
Area = 1.57 * 16 m²
So, the area of the semicircle is approximately 25.12 square meters.
