Question

Surface area of sphere round to the nearest tenth

Answer 1

Answer: 803.8

Step-by-step explanation: acellus uses 3.14 for pi, which is why a lot of answers to these questions are slightly off, as people use different values, anyway, with using 3.14 for pi, this is the answer

Answer 2

804.2

Explanation:

what ? you cannot use a calculator ? it is all there, you only need to type it in.

the only point, where you need to "think" is the difference between radius and diameter. because the graphic gave you the diameter, and the formula asks for the radius.

so ... ... ... ... did you figure it out ?

the radius is half of the diameter, so, 8ft in this example.

S.A. stands for "Surface Area".

so, now, again, we only need to type it into the calculator.

`4 * \pi * {8}^(2)`

`4 * \pi * 8 * 8`

`4 * \pi * 64`

and the result 804.2477...

rounding it to the nearest tenth (you know, the first position after the comma) is then 804.2

you really needed help with that one ?
