Write an expression that represents the area of a circle with radius 3x^3. (For any circle with radius r, a=π r^2 = π .r .r ^.)
1 answer:
9514 1404 393
Answer:
B. 9πx^6
Step-by-step explanation:
Putting the given radius into the area formula gives ...
A = πr^2
A = π(3x^3)^2 = π(3^2)(x^(3·2))
A = 9πx^6

Answer:
Step-by-step explanation:
- x + 75 + x + 125 = 180 as supplementary (same side interior angles)
- 2x + 200 = 180
- 2x = -20
- x = -10
