Answer:
√37
Step-by-step explanation:
<span>Since angle B and angle C are congruent, angle BDA is a right angle, and the sides of angle B and C have to be congruent, since the angles are congruent, Triangle BDA and Triangle CDA are both congruent, by the Angle-Angle-Side Theorem, which is the criterion that fits this answer.</span>
Answer is 50.24 m2.
Step by step.
Area is found with the formula A=pi radius squared.
We know radius is 1/2 diameter, so radius is 4.
Fill in the formula A = (3.14) (4^2) = 50.24 m2
