For each quantity, decide whether circumference or area would be needed to calculate it. 1. The distance around a circular garden
2. The amount of fabric needed to make a circular tablecloth
3. The equator of the Earth
4. The amount of cheese it takes to cover a circular pizza

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
