1/3 of 6 1/2 multiply 3/4 (56 divide by 7) pls help me

1/3 of 13/2 * 3/4(56/7)

= 1/3 of 13/2 * 3/4*8

= 13/6 * 3/4*8

= 13/6 *6

= 13

Hope this helps.

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
