C step-by-step the coordinate of that is pretty simple to say but hard at the same time
(4 times 4 times 5) + (5 times 10 times 8) = 480 in cubed.
To calculate the sine of an angle, simply divide the length of the opposite side, 479.16, by the length of the hypotenuse, 610. To get the cosine, divide the length of the adjacent side, 377.5, by the length of the hypotenuse, 610.
Answer:
A = pi * r^2 = pi * 5^2 = 25*pi = 78.54 in²
