Answer:
4/3
Step-by-step explanation:
If the ratio between the volumes of the first and the second cube is 64, the ratio between the sides is the cubic root of the ratio between the volumes, so:
Doing the same for the second and third cubes, we have:
So the ratio of the first cube side and the third cube side is:
<em><u>Question:</u></em>
The surface area of a sphere can be approximated as follows:
Surface area = 4πr2;
where r is the radius of the sphere;
π is a constant that is roughly equal to 3.
Calculate the surface area of a sphere with a radius of 7 meters using the simple approximation above.
<em><u>Answer:</u></em>
<h3>The surface area of a sphere is 588 square meter</h3><em><u>Solution:</u></em>
<em><u>The surface area of a sphere is given as:</u></em>
Where, "r" is the radius of sphere
π is a constant that is roughly equal to 3
From given,
Radius = 7 meter
<em><u>Substitute r = 7 in given formula</u></em>
Thus the surface area of a sphere is 588 square meter
