A unit circle has its center at the origin and has a radius of one. It is modeled by the equation
x² + y² = 1
We are given with <span>(x,-1)</span> .
Solving for x
x² + (-1)² = 1
x = 0<span />
9x – 3y – 5x + 7y + x + y
9x-5x+x -3y+7y+y
x(9-5+1) +y(-3+7+1)
5x+5y
Choice C
Answer:
Volume of cylindrical tank is 2122.64 cubed feet.
Step-by-step explanation:
It is given that:
Radius of cylindrical tank = 6.5 feet
Height of tank = 16 feet
Volume of tank = πr²h
Putting the values in the formula
Volume = 3.24 * (6.5)² * 16
Volume = 3.14 * 42.45 * 16
Volume = 2122.64 cubed feet.
Therefore,
Volume of cylindrical tank is 2122.64 cubed feet.
