What's the approximate area of a segment of a circle with a height 6 m and the length of the chord is 20 m? round your answer to the nearest whole number.

Area = 85.4 m^2

Explanation:

Given data:

height h  = 6 m

length l = 20 m

we know that chord length is given as

solviing for radius r we get

r = 11.33 m

we know that area of segment of circle is given as

r - h = 11.33 - 6 = 5.33m

r -h = 11.33 - 6 = 68  m^2

Area = 85.4 m^2

e. denser plates slide under lighter plates.
