Question

Find the area of circle x that has a radius at coordinates X = (0, 3) and Y = (-3, -1). Round to the nearest tenth.

Answer 1

Answer:

• 78.5 units²

Step-by-step explanation:

Area of circle:

• A = πr²

Distance between x and y is same as r, so:

• r² = (0 + 3)² + (3 + 1)² = 9 + 16 = 25

Then the area is:

• A = π*25 = 78.5 units² (rounded)
