The depth of a lake is 15.8m
a. jada accurately measured the depth of the lake to the nearest meter. what measurement did jada get
b. by how many meters does the measured depth differ from the actual depth?
c. express the measurement error ad a percentage of the actual depth.

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

y=sec x is the correct answer
