Answer:

Step-by-step explanation:
Assuming this pizza is a circle, we can use this formula for area:

1. Find Radius
We are given the diameter: 12 inches, but the formula uses radius.
The radius is half the diameter, or:



2. Calculate Area
Substitute the radius (6 inches) in for r. The question also asks us to use 3.14 for pi.

Solve the exponent.
- (6 in)²= 6 in* 6 in= 36 in²

Multiply.

3. Round
The question asks us to round to the nearest tenth.
The 4 in the hundredth place tells us to leave the 0 in the tenth place.

The area of the pizza is about 113.0 square inches.
Answer:
(-3, -2)
Step-by-step explanation:
The transformation (x, y) ⇒ (y, -x) represents a rotation of 270° CCW about the origin (or 90° CW).
This transformation maps the point Q(2, -3) to Q'(-3, -2).
