Gabby plans to hike 6.3 kilometers to see a waterfall. she stops to rest after hiking 4.75 kilometers. how far does she have left to hike?

1.55 Km

Step-by-step explanation: She hiked 4.75 Km of 6.3 Km, so we subtract.

Remember to add a 0 next to three, and arrange the decimal points so there are one above another. Also remember to put the greater number on top of the smaller, and if a digit on top is smaller than the bottom, carry from the right. This is the most important thing: DO NOT FORGET THE DECIMAL POINT!

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
