Question

9. If the radius of the Earth is 6.37 x 106 m and the
radius of the Moon is 1.74 x 106 m, compare the
diameter of the Earth to that of the Moon.​

Answer 1

r=2d

R=radius of earth= 6.37×106m

r=radius of moon= 1.74×106m

D=Diameter of Earth=2×6.37×106m

d=diameter of moon=2×1.74×106m

Comparing diameter of earth and moon

$\frac{2 \times 6.37 \times 106m}{2 \times 1.74 \times 106m}$

$\frac{6.37}{1.74} = 3.6609$

HERE IS YOUR ANSWER.

Answer 2

Answer

• Diameter of sun > Diameter of moon

Explanation

Given

• Radius of the earth = 6.37 × 10⁶
• Radius of the moon = 1.74 × 10⁶

To Find

• Compare the diameter of the Earth to that of the Moon.

Solution

Firstly, converting to usual form,

→ Radius of the earth = 6.37 × 10⁶ = 6370000

→ Radius of the moon = 1.74 × 10⁶ = 1740000

We know that,

→ Diameter = Radius × 2

→ Diameter of the sun = 6370000 × 2

→ 12740000

→ Diameter of the moon = 1740000 × 2

→ 3480000

Now, converting to exponential form,

→ Diameter of the sun = 12740000 = 1.274 × 10⁷

→ Diameter of the moon = 3480000 = 3.48 × 10⁶

Therefore, the diameter of the sun is greater than that of moon
