Radius=8/2=4cm
volume=4*4*3.14*20=1004.8
The answer is 1004.8cm₃
Answer:11
Step-by-step explanation: think about 5+6 then when you add 11 to the -5 you get 6.
Calculate the circumference of the full circle:
circumference = PI x diameter = 3.14 x 20 = 62.8 inches
the arc length is 160 degrees of the full circle
divide 160 by 360 (full circle) and multiply by the circumference:
160/360 x 62.8 = 27.9 inches
A function has a property such as "one input must be mapped to exactly one output." An input is the x-value, and the output is, generally, the y-value. In this set of points above, the input 3 maps to 4 <em>and </em>12, and therefore is not a function.
