Question

diameters
a diameter is the distance across a circle or a sphere through its center. the earth figure shows the diameter of our planet.

1. write the diameter of earth at the equator in expanded form with exponents.

diameter at the equator = 12,756 km.

Explanation:

Step1: Break down the number

$12,756 = 10,000 + 2,000 + 700 + 50 + 6$

Step2: Rewrite as powers of 10

$10,000 = 1 \times 10^4$, $2,000 = 2 \times 10^3$, $700 = 7 \times 10^2$, $50 = 5 \times 10^1$, $6 = 6 \times 10^0$

Step3: Combine the terms

$1 \times 10^4 + 2 \times 10^3 + 7 \times 10^2 + 5 \times 10^1 + 6 \times 10^0$

Answer:

$1 \times 10^4 + 2 \times 10^3 + 7 \times 10^2 + 5 \times 10^1 + 6 \times 10^0$
