Work out the circumference of a circle with radius of 7.5cm. Taki Pi to be 3.142

C = 47.1 cm

Step-by-step explanation:

Here C = 2*pi*r.  Replacing pi with 3.142 and r with 7.2 cm, we get:

C = 2(3.142)(7.5 cm) = 47.13.  Note that because r is given to 1 decimal place, your area should be expressed to 1 decimal place also:  C = 47.1 cm

no because after the troops were pulled many blacks were killed by hangings lynchings and other cruel ways which in a way interrupted the reconstruction of the south and differed from the way abraham lincoln had an idea of reconstruction
