Question

If the radius of a spherical orange is 3.5 cm. find its surface area and volume​

Answer 1

Explanation:

Given ,

• Radius of a spherical orange is 3.5 cm

To Find : The Surface Area and the volume of a spherical orange

In order to find the surface area of a spherical orange we use the formula,

`SA = 4\pi r^(2)`

`SA = 4X(22)/(7) X 3.5X3.5`

`SA =`
`154cm^(2)`

And now to find the volume of a sphere

`V = (4)/(3) \pi r^(3)`

`V = (4)/(3) X (22)/(7) X (3.5)^(2)`

`V`
`= 179.59cm^(2)`

Hence, the surface area is 154
`cm^(2)`and the volume of a sphere is
`179.59cm^(2)`

Answer 2

The surface area of a sphere is given by the formula:

surface area = 4 * pi * r^2

Where r is the radius of the sphere.

Using this formula, the surface area of an orange with a radius of 3.5 cm is:

surface area = 4 * pi * (3.5 cm)^2

= 4 * pi * 12.25 cm^2

= 49.0307 cm^2

The volume of a sphere is given by the formula:

volume = (4/3) * pi * r^3

Where r is the radius of the sphere.

Using this formula, the volume of an orange with a radius of 3.5 cm is:

volume = (4/3) * pi * (3.5 cm)^3

= (4/3) * pi * 42.875 cm^3

= 113.097 cm^3
