To divide like bases just subtract the exponents
answer is 2^(13-3) or 2^10 or 1024
5 hundred is 500
8 tens is 80
So 5 hundred 8 tens is <em><u>580</u></em>
1) 12 * 9 = 108 cm² - part 1
2) 12 - 3 - 3 = 6 cm
3) 6 * 4 = 24 cm² - part 2
4) 108 + 24 =
132 cm ² - the area.
Pi is multiplied by diameter so,
35 x pi= 109.995
