Answer:
A- A teacher has 12 girls and 15 boys in her class.
Step-by-step explanation:
12/3= 4
15/3= 5
This means that it will have a ratio of 4 to 5 because it is the only problem where you are able to divide both with a common number, which is 3.
Answer:
The circle has a greater area than the triangle.
Step-by-step explanation:
Area of a triangle:
Area of a circle:
We are given the base and the height of the triangle, 50 ft and 50 ft respectively.
Substitute these values into the formula for the area of a triangle.
- Aₜ = 1/2(50)(50)
- Aₜ = 1/2(2500)
- Aₜ = 1250 ft²
The area of the triangle with a base of 50 ft and a height of 50 ft is 1250 ft².
We are given the diameter of the circle, 50 ft. We need the radius of this circle, so we can divide the diameter by 2 to get r = 25 ft.
Substitute this value for r into the formula for the area of a circle.
- A꜀ = π(25)²
- A꜀ = π(625)
- A꜀ = 1963.49540849 ft²
The area of the circle with a radius of 25 ft is 1963 ft².
<em>Therefore, the circle has a greater area compared to the triangle.</em>
