Answer:
5/6π(4.25 in)^2
Step-by-step explanation:
Step 1: Calculate the full area of the disk using the formula for the area of a circle: A = π × r2
A = π × (4.25 inches)2
A = 56.41π inches2
Step 2: Calculate 5/6 of the full area.
A = (5/6) × 56.41π inches2
A = 47.01π inches2
Therefore, the area of 5/6 of the disk is 47.01π inches2.
