Hello
cos ( x + pi/2) =cos(x)cos(pi/2)-sin(x) sin(pi/2)
= cos(x)×0-sin(x) ×1
cos ( x + pi/2) = - sin(x)
Answer:
Cylinder Surface Area = (2 • π • r²) + (2 • π • r • height)
Surface Area = (2 * PI * 7^2) + (2*PI*7*22)
Surface Area = 307.8760800518 + 967.6105373057
Surface Area = 1,275.4866173575 Square Inches
Cylinder Volume = π • r² • height
Volume = PI * 7^2 * 22
Volume = 3,386.6368805698 Cubic Inches
Surface Area to Volume = 1,275.4866173575 / 3,386.6368805698 =
0.3766233766
