Answer:

511.04m^2

Step-by-step explanation:

A circular hot spring has diameter of 110 meters. Over time, the diameter of the spring decreases by 3 meters. By how many square meters does the area of the hot spring decrease

Area of a circle = πr²

Where : = π = pi = 3.14

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

3.14 x (110/2)² = 9498.5

Diameter after decrease = 110 - 3 = 107

3.14 x (107/2)² = 8987.5

Decrease in area = 9498.5 - 8987.5 = 511.03
