Formula for Diameter: <span>2 x radius
Formula for Radius: R= C/2(pi)</span>
R= 176/2(22/7)
R=28.01
2(28.01)=56.02
Answer= 56.02
Alrighty, so 280.05 rounded to the nearest integer is 280. 280.05 rounded to tenths is 280.1. add those two together and you get 560.1.
It is hard to see the questions in the picture.
Answer:
the slope is -1/7 hope this helps
Supplementary angles add to 180
4+5=9
180/9=20
4*20=80
5*20=100
the angles are 80 degrees and 100 degrees
