What is the best approximation for the area of a semi-circle with a diameter of 11.8 ( Use 3.14 for pie

Sagot :

Answer:

54.7units^2

Explanation:

Area of a semi-circle = \pid^2/8

d is the diameter of the semi circle

Given d = 11.8

Area = 3.14(11.8)^2/8

Area of the semi circle = 3.14(139.24)/8

Area of the semi circle = 437.2136/8

Area of the semi circle = 54.6517units^2

Hence the best approximation is 54.7units^2
