Answer:
Area of Mrs. Margarita's garden = 1188.39 m²
Step-by-step explanation:
Using the most basic formula to solve this question i.e. Area of circle. We know that: Area of of circle = πr². But in problem we are provided with a half shaped circle. Means we need to use the half of the area of circle or you can say semi-circle.
Area of semi-circle = 1/2 × πr²
Now, read the question again. Mrs. Margarita has a garden shaped like a half-shaped circle with a diameter of 55 m. Given diameter is 55 m and we know that radius is half of the diameter. So, radius is 55/2 m. Rest what we need to do is substitute the values and do the rest calculations.
Let's dive in!
Area of Mrs. Magarita's garden = Area of semi-circle or area of half-shaped circle
= 1/2 × 22/7 × 55/2 × 55/2
= 11/7 × 55/2 × 55/2
= 33275/28
= 1188.39 m²
