A target with a diameter of 28 cm has 4 scoring zones formed by concentric circles. The diameter of the center circle is 4 cm. The width of each ring is 4 cm. A dart hits the target at a random point. Find the probability that it will hit a point in the blue region.

the answer is 11.2 (i know i’m late)

18 units²

step-by-step explanation:

first let's find altitude bd using the distance formula

d = √((y₂ - y₁)² + (x₂ - x₁)²)

bd = √((0 - -3)² + (0 - 3)²)

bd = √18

given the placement of points a and c, we can denote that point d bisects segment ac.

we will call ac the base.

using the distance formula

ac = √((0 - 6)² + (-6 - 0)²)

ac = √72

knowing our base and our height, we can plug these into our triangle area formula

area = (b * h)/2

area = (√18 * √72) / 2

area = (√1296) / 2

area = 36 / 2

area = 18 units²
