Answer:
Circumference is 12.56
Area is 6.28
Step-by-step explanation:
4×3.14=12.56
2×3.14=6.28
A.)

Y intercepts:(0,-3)
40º
7) In this problem, we can see that both tangent lines to that circle come from the same point O.
So, we can write out the following considering that there is one secant line DO and one tangent line to the circle AO

Answer:
95
Step-by-step explanation:
let x be his mark in the fourth test, then
mean =
= 83 ( multiply both sides by 4 )
83 + 81 + 73 + x = 332
237 + x = 332 ( subtract 237 from both sides )
x = 95
