Final answer:
The tumor measures 38 mm in diameter. Converting millimeters to inches, the size of the tumor is approximately 1.50 inches.
Step-by-step explanation:
The tumor measures 38 mm in diameter, and we need to find its size in inches. To convert millimeters to inches, we can use the conversion factor 1 inch = 25.4 millimeters.
We can set up a proportion to solve for the size of the tumor in inches:
38 mm = x inches
Using the conversion factor, we can write the proportion as:
1 inch / 25.4 mm = x inches / 38 mm
Cross-multiplying and solving for x gives:
x = (1 inch x 38 mm) / (25.4 mm)
Calculating the value of x, we find:
x = 1.50 inches
