Step-by-step explanation:
V= 3.14*5^2*28/3
Order of Operations (PEMDAS)
5^2=25
25*3.14= 78.5
78.5*28= 2198
2198/3=732.66

Answer:
15.22
Step-by-step explanation:
The equation of the circumference of a circle is 2(pi)r
This is actually because 2pi is angle of the arc that makes up the full circle (radians of course)
so a simple formula is:
arc length in radians X radius
radius = 4 cm
the area that the question wants is the oposite
of the 142 degree section so 360 - 142 = 218
218 degrees * (pi/180) = 3.80482 rad
3.80482 * 4 = 15.21928 cm
