Question

Calculate the surface area of the egg (in μm2). The formula for calculating the surface area (SA) of a sphere is given below. SA = 4Ïr2. Use 3.14 as the value for Ï.

Answer 1

`31400\mu m^2`

Explanation:

We are given that

Diameter of egg,d=
`100\mu m`

We have to find the surface area of egg in
`\mu m^2`.

Radius of egg,r=
`(d)/(2)=(100)/(2)=50\mu m`

Surface area of sphere=
`4\pi r^2`

Where
`\pi=3.14`

Using the formula

Surface area of egg=
`4* 3.14(50)^2`

Surface area of egg=
`31400\mu m^2`

Hence, the surface area of the egg=
`31400\mu m^2`
