What is the approximate area of the sector given 1.6 radians with diamator of 9

Area of a circumference=π*r²for diameter=21.2 cm> r=10.6 cmA=π*10.6²> A=π*112.36 > A=352.81 cm²if 2π radians (full circumference) has an area of > 352.81 cm² 3π/5 radians> XX=[(3π/5)*(352.81)]/2π> X=105.84 cm²

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

this is answer of 144 cubic meters
