Answer:
360
Area
Step-by-step explanation:
The formula of the area of a sector in a circle is:
Area of sector =
× πr², where
- x is the central angle of the sector
- πr² is the area of the sector
Example:
The measure of a central angle is 60°, and the area of the circle is 12π unit², then the area of the sector of the central angle is:
Area of the sector =
× 12π = 2π
To find the area of the sector
Divide the measure of the central angle by 360
Multiply the result by Area of the circle
A--width b--length b=864 Divided by a b=3a divided by 2 864 divided by a = 3a divided by 2 a =24 b=864 divided by 24 = 36 Answer= the length of the basement is 36 feet
Answer:
Width of the arch = 105 m
Step-by-step explanation:
Function representing the width of the arch,
f(x) = -0.016(x - 52.5)² + 45
where x = width of the base of the arch or horizontal distance from arch's left end
f(x) = vertical distance of the arch
From the given quadratic function, vertex of the parabola is (52.5, 45).
Coordinates of the vertex represents,
Height of the arch = 45 m
Half of the horizontal distance from the left end = 52.5 m
Therefore, width of the bridge = 2(Half the width of the bridge from left end) = 2×52.5
= 105 m
Therefore, given bridge is 105 m wide.
