Answer:

Circumference is 131.94

Step-by-step explanation:

Circumference Formula is C=2πr

Enter 21 for r so it will look like C=2(π)(21)

That makes it equal 131.9468915 so since you are rounding to the nearest tenth, you go next to the 4 and since it is a 6, it will round the 4 up to a 5

so that will make the answer 131.94

Hope this helps!

7.056

7 is units place = 7 *1

0 is tenth place = 0 *(1/10)

5 is hundredth place = 5 *(1/100)

6 is thousandth place = 6 * (1/1000)

7.056 = 7*1+ 0*\frac{1}{10}+5*\frac{1}{100}+6*\frac{1}{1000}

Seven and fifty six thousandths

18.3

Eighteen and one third

18.3 = 1*10 + 8*1 + 3*\frac{1}{10}

918.0201

Nine hundred eighteen and two hundred  one ten thousandths

918.0201=9*100 + 1*10 + 8*1 +0 +2*\frac{1}{100}+0+1*\frac{1}{10000}
