Find the probability that the dart lands in the shaded circular region. the radius of the dartboard is 4 in, and the radius of the shaded region is 2 in.

The required probability is 0.25.

Step-by-step explanation:

Since we have given that

Radius of the dartboard = 4 in

Area of the dartboard is given by

Radius of the shaded region = 2 in

Area of shaded region is given by

So, the probability that the dart lands in the shaded circular region is given by

Hence, the required probability is 0.25.

we are given triangle bae is congruent to triangle dea.

therefore, all sides and angles of triangle bae are congruent to all sides and angles of   triangle dea.

we could say:

< bae   ≅ < dea

< abe   ≅ < eda

< bea   ≅ < dae

because triangles are congurent, all other small parts also congurent to each other.

also < dge   ≅ < fga.

from the above statements we can see that   < dge would be congruent to < fga.
