S u r f a c e a r e a = 4 π r 2 = 4 × π × 1 6 2 = 3 2 1 6. Surface area of sphere = 4πr2 we will be using the above formula in our program to find the surface area of a sphere. The surface area of a sphere (in terms of radius) = 4πr 2 where r is the radius of the sphere.

300 = 4 X \[\Frac{22}{7}\] X R 2.

Hence the radius of the sphere is. It is an object with the shape of a rou. About press copyright contact us creators advertise developers terms privacy policy & safety how.

Find The Surface Area Of A Sphere With A Radius Of 6 Cm Sa = 4 × Pi × R 2 Sa = 4 × 3.14 × 6 2 Sa = 12.56 × 36 Sa = 452.16 Surface Area = 452.16 Cm 2 Example #2:Measure The Distance Around The Globe (Unit:if The Problem Calls For An Exact Answer, Then Leave The Answer As 100Π.

And the lateral surface area of a rectangular box is 2h(l+w). Take the square of the radius by multiplying it by itself. Calculate the area of each face.

The Lateral Surface Area Of A Sphere Is 4(Pi)R^2.

Then, multiply the squared radius by 4. Given the radius (r) of a sphere, we can find its surface area using the formula {eq}sa = 4\pi r^2 {/eq}. Surface area = 4 π r2 square units.

For Example, If The Radius Is 5, It Would Be 25 Times 4, Which Equals 100.

Now we can try to derive various surface area of a sphere formulas. Hence, the required ratio of their surface areas is 1:25. A cuboid has 6 rectangular faces.

To Find A Surface Area Of A Sphere, We Need To Find Out The Radius Of Sphere First, And Then Calculate Its Surface Area 4Πr².

For a sphere, if its diameter is given, then its surface area can be given by πd 2. You can see that the lateral surface area of a cylinder is 2(pi)rh. See the formula used in an example where we are given the diameter of the sphere.
