The given equation is 
By solving the given equation, we get


While solving the equation,we get 0=0.
Therefore, the given equation is true for all the values of y.
Hence, we can say that the given equation has infinite number of solutions.
The surface area formula for any sphere is 4(pi)(radius)^2
The radius is half of the diameter.
18.6 / 2 = 9.3
So, plug into the formula and solve.
4(3.14)(9.3)^2 = 1086.3 mm^2
The answer is 31.42 since the radius is five and then you multiply it times squared and then times 3.14
Answer:
3x+6 is inverse of 3x-6.it is a additive inverse and if we add both we get 0.
Answer:
2.20
Step-by-step explanation:
First, change 42° to radian
42/180 * π = 0.733 rad
The length of the arc = 3 * 0.733 = 2.20
