Answer:
C is the answer
Step-by-step explanation:
use the pythagorean theorem: a^2 + b^2 = c^2
6^2 = 36
4^2 = 16
36-16 = 20.
the square root of 20 is either a.) the square root of 20 or b.) 4.4721... (rounded 4.5)
90 degrees
angles are measured in degrees
-0.3048106211
exact area = 25(pi) m^2
approximate area = 78.54 m^2
diameter = 10 m
radius = diameter/2 = 10 m / 2 = 5 m
area = (pi)r^2
area = (pi)(5 m)^2
area = 25(pi) m^2
area = 78.54 m^2
