According to the blueprint, 1 centimeter corresponds to 0.8 millimeters on the microchip. Since 1 centimeter is equal to 10 millimeters, we can set up the following proportion:
1 centimeter on blueprint = 0.8 millimeters on microchip
10 millimeters on blueprint = x millimeters on microchip
To find the diameter on the blueprint, we need to double the radius. Therefore, we can multiply the 10 millimeters on the blueprint by 2:
Diameter on blueprint = 2 * 10 millimeters = 20 millimeters.
Since 1 centimeter is equal to 10 millimeters, we can convert the diameter from millimeters to centimeters:
Diameter on blueprint = 20 millimeters = 2 centimeters.
So, the diameter of the blueprint representation of the microchip is 2 centimeters.
Among the given answer choices, the closest option is D: 50.
Therefore, the correct answer is D: 50.
