after loads of calculations and stuff, i got the final answer: 62.5
is this right or not? thanks y'all
or is the answer 79.2 ?
cuz I assumed that rotating sprinkler rotates twice first so 60 degrees, not 30
which of these 2 answers is right? im confused
My answer is 79.238 m2
(square area - area of the 30 degree sector)
(96 -16.762 = 79.238)
1) Area of a sector of circle = (area of a circle )* (Degree angle of the sector / 360)
..[30/360 = 1/12 is like the sector is one part of the whole 12 parts of the whole area of (pi r 2 )]...
(pi * 82 ) * (1/12) = 16.7619m2
2) The dry area of the garden : Garden area - 16.7619 = 79.238 m2
