Answer:
<h3>$1,043.74</h3>
Step-by-step explanation:
Area of the circular floor = πr²
Since the stage only occupies a quarter circle section of the floor, then;
Area of the stage = πr²/4
Given
diameter of the floor = 13yd
radius = 13/2 = 6.5yd
Find the area of the stage;
Area of the stage = π(6.5)²/4
Area of the stage = 3.14(42.25)/4
Area of the stage = 33.16625yd²
If the material for the stage will cost $31.47 per square yard, this means;
1yd² = $31.47
33.16625yd² = x
Cross multiply
x = 33.16625*31.47
x = 1,043.74
Hence the stage will cost $1,043.74
Area = perimeter + 132.
Let each side of the city be x miles long, then:-
x^2 = 4x + 132
x^2 - 4x - 132 = 0
x = [-(-4) +/- sqrt((-4)^2 - 4 * 1 *-132)] / 2
x = 13.66, -9.66 We ignore the negative
So the city has dimension of 13.66 * 13.66
13.7 * 13.7 to nearest 10th
Answer:
x = 18.4
y = 22.5
Step-by-step explanation:
to find 'x':
x = √13² + 13²
x = √169 + 169
x = √338
x = 18.4
to find 'y':
y² = 13² + (√338)²
y² = 169 + 338
y² = 507
y = √507
y = 22.5
The y-value of Function A when x = 6 is greater than the y-value of Function B when x = 6.
X=27
