Answer:
251.33 yd^2
Step-by-step explanation:
The formula of surface area of cylinder is A=2πrh+2πr^2.
2πrh is the lateral surface and 2πr^2 is the 2 circles.
When you plug in the numbers 2π(5)(3)+2π(5)^2=251.33 yd^2
I believe x is 30 degrees.
The equilateral triangle has each angle equal to 60 degrees. So the small arc near x is also 60. The angle x is half the arc so would be 30.
This also makes sense because the triangle it forms with angle x and the center has center angle of 60 and angle formed by tangent and radius of 90. So it is a 30-60-90 triangle, making angle x 30.
8/2 = 4 and 35/7 = 5 so 4+5 is 9
The answer is 9
Hope this helps :)
