What is 3/20 a natural number, whole, number integer ,or rational number

rational number

Step-by-step explanation:

3/20=0.15

the natural numbers are

1,2,3,4,5,6,7... and so on

the whole numbers are

..., -3,-2,-1,0,1,2,3,... and so on

the rationals are for explame

1/2, 1/3, 2/8

so 3/20 is a rational number

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
