Approximate the area under the graph of f(x)=4−x^2 with 4 equal intervals (n=4) from x=−2 to x=2 using a) left endpoints,

b) right endpoints,

c) midpoints.

c brainliest plz ( and also plz thank my answer )

Step-by-step explanation:

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
