A unicycle tire can travel 7.85 ft. in on revolution. What is the area of the unicycle tire? Round answer to the nearest tenth.

4.9ft^2

Step-by-step explanation:

7.85 ft is the circumference of the tire (circle), so d = 7.85.

7.85/ = 2.5, the diameter is 2.5, so the radius is 1.25.

r^2 is the formula for the area, so *1.25^2 = 1.5625, which is 4.906, which rounded to the tenth is 4.9.

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
