Answer:
√(V / π × h), where V is the volume of the cylinder, h is the height, and π(Pi) is a mathematical constant with an approximate value of 3.14
Answer:
H = 1781
Step-by-step explanation:
First, find the radius which is 9; 18/2. Then use cyclinder formula pi*r^2*h. Substitute values, but replace height with 6 because you are finding volume of water. Equation: pi*9^2*6
We are given the angle measure, measure of hypotenuse and we are to find the base(Adjacent) side of the angle.
Cosine relates all these three as:
Rounded to nearest hundredth, the measure of side adjacent to the angle is 1.88
Answer:
x^2+12x-13 = 0
Step-by-step explanation:
12x=13-x^2
=>12x+x^2=13-x^2+x^2
=>x^2+12x-13 = 13-13
=> x^2+12x-13 = 0
