Question

the side of a triangular park are 8m 10m and 6m respictevely a small circular area of a diameter 2m is to be left out and the remaining area is to be used for growing roses how much area is used for growing roses use pie 3.14<br />

Answer 1

Semiperimeter of triangular park = (8+10+6)/2 = 12m.

Area of triangle heron's formula = Root {12(12-8)(12-10)(12-6)} = 24m2

Area of circle to be left out = Pie X (2/2)2 = 3.14m2

Area used for growing grasses = Total area - area to be left out = 24m2 - 3.14m2 = 20.86m2
