Question

find the volume of a planet, radius is 3 × 10^5 ?​

Answer 1

Answer:

If planet is assumed to be perfect sphere

Volume=4/3 ×π×(3×10^5)^2=3.74×10^11 (approximately)

Answer 2

$\huge\purple{ANSWER:}$

Volume of Sphere = 4/3 × π × r³

Now, put the values →

$\frac{4}{3} \times \pi \times( 3 \times {10}^{5} )^{3}$

$\frac{4}{3} \times \frac{22}{7} \times {(300000)}^{3}$

$\frac{88}{21} \times 27000000000000000$

$\frac{88}{7} \times 9000000000000000$

$12.5714286 \times 9000000000000000$

$= 113142857000000000 \: {m}^{3}$
