Melania walked her dog 2 1/5 miles. cathy walked her dog 1 3/4 times as far as melania did. how many more miles did cathy walk her dog

1  13/20

first multiply 2 1/5 and 1 3/4 you will get 3 17/20

then subtract from 3 17/20 - 2 1/5 you will get 1 13/20

n

step-by-step explanation:

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
