Work out the perimeter of this semicircle. Take it to be 3.142 and write down all of the digits given by your calculator.
18 cm give your answer in cm​

46.278cm

Step-by-step explanation:

(π+2)r

=πr+d

=9π+18=46.278cm

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
