First you need to find the r, if C=2pieR, than 2.4=2pieR now you divide 2.4 by 2 so you got 1.2=pieR now you divide 1.2 by pie and obtained aproximately 0.38 miles, that is your R, now you do pie multiply by 0.38 exposant 2 and there you go, your answer is aproximately 0.45 miles2 :)
Put the equation in standard linear form.

Find the integrating factor.

Multiply both sides by
.

Now the left side the derivative of a product,

Integrate both sides.

On the right side, integrate by parts.

Solve for
.

40(105/100)=42

Answer:
36
Step-by-step explanation:
EF = is 1/3 of 15
Since the triangles are similar, then the perimeters are similar.
The perimeter of EDF is 12
The perimeter of ABC should be 3 times as large.
3*12 = 36
The perimeter of ABC = 36
Answer:
- b. 25.7 + 13.2 + 6.4 = 45.3
Step-by-step explanation:
25.65 ≈ 25.7, 13.23 ≈ 13.2, 6.35 ≈ 6.4
- 25.65 + 13.23 + 6.35 =
- 25.7 + 13.2 + 6.4 =
- 45.3
Correct choice is b.
