The area of the WHOLE circle is the area of the central angle of 2pi
Let's set up a ratio 2pi / (3pi/13) = x / 19
and solve for 'x' = 2pi / (3pi/13) x 19 = 26 / 3 x 19 = 494 / 3 =164 2/3 m^2
Just add the 'like terms'
(7+(-8)) + (3i+9i) = -1 + 12i
3 2/5 as a decimal. The '3' will still be a '3' and you just divide the 2 by 5 for the decimal fraction to get : 3 . 4
Is that 1,092 . 58 ? = 3.03845
use the ' / ' symbol for division
1.6 x 10^9 x 1/100 = 1.6 x 10^7
1,600,000,000 x 1/100 = 16,000,000 16 million
>>>>......BUT make sure your UNITS are CONSISTANT !!!!!
One possibility is 35 22 23 y/o
a(a+5) looks simplified to me, we can expand it to a(a) + 5(a) = a^2 + 5a
We CAN answer word problems if given enough information or digrams if referenced !
