A triangle has side lengths of (2.6c + 8.2d) centimeters, (7.3c + 4.6f) centimeters, and (6.5f + 3.6d) centimeters. Which expression represents the
perimeter, in centimeters, of the triangle?
1. 16.4cf + 16.4df
2. 11.1f +9.9c + 11.8d
3. 11.9cf + 10.1df + 10.8cd
4. 9.9c + 8.2f + 14.7d

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

i suppose it should be (y=2x-5)

answer:

probably the same as it is today since you did not eat the corn dogs yet

step-by-step explanation:

given the equation is 8+9z=-6, the first step would be to subtract the 8 from both sides:

8+9z-8=-6-8

since 8 minus 8 = 0, this would cancel out the 8. and since -6 minus 8 equals -14, the equation would look like this

9z = -14
