Find the surface area of a cylinder in terms of pie.
Radius is 9 and height is 20.

522π

Step-by-step explanation:

formula: 2πr^2+2πrh. square= ^2 radius= r height= h

2π(9)^2+2π(9)(20)

162π+2π(180)

162π+360π

result= 522π

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
