Answer:
6.25h=50
Step-by-step explanation:
Surface area of a cone is pirs+pir^2
SA=3.14*10*18.2+3.14*10^2
SA=571.48+314
SA=885.48
Answer:
66
Step-by-step explanation:
angle 1 and 4 are supplementary so the 2 added together equal 180. 180-124=56.
The sum of the triangles angles equal 180
180-56-58=66 which is the value of angle 2
Given:
The figure of a right angle triangle.
To find:
The value which is equal to r÷q.
Solution:
In the given right triangle, the length of the hypotenuse is q units.
For angle x degrees, perpendicular is p units and base is r units.
For angle y degrees, perpendicular is r units and base is p units.
In a right angle triangle,


So,


Therefore, the value of r÷q is equal to siny or cosx. So, the correct option is C.
The answer is 20.25 because .9 squared is .81 so you times .81 to 5 squared and you get 20.25
