The area of the shaded sector is one-fourth of the area of the whole circle so:

area of shaded region

The area of the shaded region is 9pi units^2
Let's write the equation with formula:-

Where,
- x1 is -1 and y1 is 4 and m is 3





<em>Thus, The correct choice is option C!!~</em>
Answer:
The correct answer to this question is A) 19 cubic feet of snow
Step-by-step explanation:
To solve this, use the equation V = 4/3 (π r^3) to get the volume of each. Then add all the volumes together: (1ft x3.14) + (2ft x3.14) + (3ft x3.14). You will get 19 cubic feet of snow. This is how much snow is needed to build the whole snowman.
