Question

The diameter of planet venus is 12278 km find its circumference π=22/7

Answer 1

Radius = Diameter/ 2 = 12278/2 = 6139 km

Circumference of the circle = 2πr
= 2*22/7*6139
= 38552.92 km

Hence, circumference of the circle is 38552.92 km

Hope this helps you

Answer 2

Answer: -The circumference of the planet Venus = 38,588 Km.

Detailed solution: -

Given: -

The diameter of the planet Venus (d) = 12278 Km

In the question it is said to use the value of π = $22/7$.

We need to find the circumference of the planet Venus.

To find the circumference of the planet, first we need to find the radius of the planet from the given diameter.

The formula to find the radius from the given diameter is -

Diameter (d) = $2*radius$

Therefore,

Radius (r) = $diameter / 2$

$r=12278/2Km\\r=6139Km$

Therefore,

Radius of the planet (r) = 6139 Km

Now,

We can find the circumference of the planet Venus by using the circumference of the circle formula.

The circumference of the circle = 2πr

$=2*\frac{22}{7}*6139Km\\ =2*22*877Km\\=44*877Km\\=38588Km$

• The denominator 7 will divide the radius and get 877 as its answer. Then all the left values will be multiplied together to get the final answer.

Therefore,

The circumference of the planet Venus = 38,588 Km.
