Answer:
The area of rug is 48.9 m^2
Step-by-step explanation:
Let's assume radius of rug is r m
we know formula for circumference as
we are given
C=24.8
and then we can solve for r
now, we can use area formula
we can plug r
and we get
So,
The area of rug is 48.9 m^2
Answer:
A triangular prism
Step-by-step explanation:
The 3 rectangles represent 3 sides of the prism. Imagine folding on the line, and connecting the left side of the first rectangle to the right side of the third rectangle. It will make a triangle that has depth.
Looking that the top and bottom triangles attached to the third rectangle shows us that the top and bottom of this shape are triangles, which matches the three sides.
What we have is a 3D triangle, which we call a triangular prism
Answer:
circle: 6490.9 cm², quadrant: 1622.7 cm²
Step-by-step explanation:
The circumference of the entire circle is known as 2πr and it is 4 times the given value, since a circle has 4 quadrants:
2πr = 4·71.4 = 285.6, so r = 285.6 / 2π ≈ 45.45
The area of a circle is πr², filling in the value for r we just found:
πr² = π 45.45² ≈ 6490.9 cm²
So the area of a quadrant is one fourth of that:
6490.9/4 = 1622.7 cm²
The question about "its area" can denote the entire circle, or just the quadrant, so two answers are provided.
