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.
