Answer:
5π m
Step-by-step explanation:
Using the pythagorean theorem we can figure out that the third side is 5m
A^2 + B^2 = C^2
3^2 + 4^2 = C^2
9 + 16 = C^2
25 = C^2
√23 = √(C^2)
C = 5m
Side C is also the diameter of the circle, so the radius is 5/2, or 2.5
From that we can use the circumference formula, Circumference = 2π<em>r</em>
Circumference = 2 π (2.5) = <u>5π m</u>
1. 6 (3)^2 = 54 ft ^2
2. 6 (2)^2 = 24 ft ^2
3. 54+ 24 = 78 ft^2
That answer is correct, 9x + 4 -5y. Only like terms are the x terms and we add 3 and 6 together.
....the answer is 682.5
