PLS ANSWER(25 POINTS)

Circle A has a diameter of approximately 20 inches and an area of approximately 300 in². Circle B has a diameter of approximately 60 inches. Which of these could be the area of Circle B?
1. About 100 in²
2. About 300
3. About 900 in²
4. About 2,700 in²

4. About 2,700 square inches

Step-by-step explanation:

Circle B's diameter is 60 inches.

Radius = 1/2 diameter, so it's 30 inches.

Area = πr^2

        = π(30^2)

        = 900π = about 2827 square inches, which is closest to

                                                  4. About 2,700 square inches

4. about 2700

Step-by-step explanation:

30^2×3.14

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.

i think that you should ask google for the answer to that problem because if we don't know it google does
