The minute hand of a clock is 15 cm long how far does the tip of the minute and travel in 20 minutes

1 answer:

4 0

20 mins means the hand moves 120 degrees around the clock.

The formula to find the arc length is 2pi×r×a/360

2×pi×15×1/3=30pi×1/3=10pi

so i think the answer would be 10 pi cm

A sandwich costs 5:70 and a piece of fruit costs 2:15 if you have a 20 bill, how much change will you get ?

Gelneren [198K]

Well if you buy only 1 of each, it would cost you 7.85 in total. if you subtract that from 20, it equals 12.15.
you can also make it a linear equation if you want more or less than 1 fruit and or sandwich
s=sandwich
f=fruit
5.7f+2.15f=20
