Question

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

Answer 1

Answer:

16πa²b²c²

Step-by-step explanation:

r = 2abc

SA = 4πr²

= 4π x (2abc)²

= 4π x 4a²b²c²

= 16πa²b²c²

Answer 2

Answer:

area of sphere: 16πa²b²c²

Explanation:

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

$\sf where \ r \ is \ radius$

Here given,

• radius: 2abc

using the formula:

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

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

$\sf \hookrightarrow 4\pi (2abc)^{2}$

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

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

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