Answer:
C) x = 20.8
Step-by-step explanation:
Since the line with the length equal to 6 forms a right angle on line x then we know it is perpendicular and bisects it.
Plug in the values: a^2 + b^2 = c^2
a^2 + 6^2 = 12^2
a^2 + 36 = 144
a^2 + 36 - 36 = 144 - 36
a^2 = 108
√a^2 = √108
a = √108
a = 10.3923048454
a = 1/2 x
2a = x
2(10.3923048454) = x
x = 20.7846096908
x = 20.8
Answer: altitude at starting point is -11ft or 11ft below sea level
Step-by-step explanation:
Equation for this situation will be
A = Ag - 11
A = actual altitude
Ag = altitude gained.
At starting point, altitude gained is zero, therefore;
A = 0 - 11
A = -11ft
The surface area of the cylinder is 1570.8
Answer:
A. 346.19 square feet.
Step-by-step explanation:
We have been given that a contractor has been hired to install flooring for a bandstand in the shape of a circle that is 21 feet across.
To find the square feet of flooring required, we will find area of circle.
Since the length across the circle is 21 feet, so radius of circle will be half of 21 feet.
Therefore, 346.19 square feet of flooring will be required.
