the diameter of earth is 7928 miles. what is the diameter in inches? in yards? If the diameter of earth is expressed in 12,756km what is the diameter in meters? in centimeter? give yoiur answers in scientific notation

Mile = 1760 yards = 1760 * 36 inches

km = 1000 meters = 1000 * 100 centimeters

Scientific notation: km = 10^3 meters = 10^5 centimeters

I'll let you do the calculations.

To convert the diameter of Earth from miles to inches, we need to know that there are 5,280 feet in a mile and 12 inches in a foot.

Therefore, to convert miles to inches, we multiply the number of miles by 5,280 (feet/mile) and then by 12 (inches/foot).

Diameter of Earth in inches = 7928 miles × 5280 feet/mile × 12 inches/foot

Calculating this:

7928 × 5280 × 12 = 499692480 inches

Hence, the diameter of Earth is approximately 499,692,480 inches.

To convert the diameter of Earth from miles to yards, we need to know that there are 1,760 yards in a mile.

Diameter of Earth in yards = 7928 miles × 1760 yards/mile

Calculating this:

7928 × 1760 = 13,953,280 yards

Therefore, the diameter of Earth is approximately 13,953,280 yards.

Now, let's convert the diameter of Earth from kilometers to meters and centimeters. We know that there are 1,000 meters in a kilometer and 100 centimeters in a meter.

Diameter of Earth in meters = 12,756 kilometers × 1,000 meters/kilometer

Calculating this:

12,756 × 1,000 = 12,756,000 meters

Thus, the diameter of Earth is approximately 12,756,000 meters.

Diameter of Earth in centimeters = 12,756 kilometers × 1,000 meters/kilometer × 100 centimeters/meter

Calculating this:

12,756 × 1,000 × 100 = 1,275,600,000 centimeters

Hence, the diameter of Earth is approximately 1,275,600,000 centimeters.

In scientific notation, the answers would be:
- Diameter of Earth in inches: 4.9969248 × 10^8 inches
- Diameter of Earth in yards: 1.395328 × 10^7 yards
- Diameter of Earth in meters: 1.2756 × 10^7 meters
- Diameter of Earth in centimeters: 1.2756 × 10^9 centimeters

To convert the diameter of Earth from miles to inches, multiply the value by 5,280 (the number of feet in a mile) and then by 12 (the number of inches in a foot).

Diameter in inches: 7928 miles * 5280 feet/mile * 12 inches/foot = 499,660,160 inches.

To convert the diameter of Earth from miles to yards, divide the value by 1,760 (the number of yards in a mile).

Diameter in yards: 7928 miles / 1760 yards/mile = 4,504.545 yards.

To convert the diameter of Earth from kilometers to meters, multiply the value by 1,000 (since there are 1,000 meters in a kilometer).

Diameter in meters: 12,756 km * 1,000 meters/km = 12,756,000 meters.

To convert the diameter of Earth from kilometers to centimeters, multiply the value by 100 (since there are 100 centimeters in a meter).

Diameter in centimeters: 12,756 km * 100,000 centimeters/km = 1,275,600,000 centimeters.

Expressing the answers in scientific notation:

Diameter in inches: 4.9966016 × 10^8 inches.
Diameter in yards: 4.504545 × 10^3 yards.
Diameter in meters: 1.2756 × 10^7 meters.
Diameter in centimeters: 1.2756 × 10^9 centimeters.
