Answer:
81π cm²
OR
≈254.34 cm²
Step-by-step explanation:
The area formula for a circle is π×r².
Since the radius of the pizza is 9, we get:
π×9²=
2×π×81=
81π or ≈ 254.34 cm²
Step-by-step explanation:
Let x be the size of 1 of the 2 congruent angles.
The size of the other congruent angle is also x.
Since sum of angles in a triangle = 180°,
Measure of 3rd angle in the triangle
= 180° - 1st angle - 2nd angle
= (180 - 2x)°.
