No rush for a answer help is very much needed :))

Answer 1

area of sphere: 16πa²b²c²

Step-by-step explanation:

`\sf surface \ area \ of \ sphere = 4\pi r^2`

`\sf where \ r \ is \ radius`

Here given,

• radius: 2abc

using the formula:

`\sf surface \ area \ of \ sphere = 4\pi r^2`

`\sf \hookrightarrow 4\pi r^2`

`\sf \hookrightarrow 4\pi (2abc)^(2)`

`\sf \hookrightarrow 4\pi (2^2 a^2 b^2 c^2)`

`\sf \hookrightarrow 2^2\cdot \:4\pi a^2b^2c^2`

`\sf \hookrightarrow 16\pi a^2b^2c^2`
