At 16:43 do you not put ANS in the brackets because the radius was rounded to 1 d.p?

[@Fundszino]

Is this higher as well?

[@shemyemantecle4703]

Of course

[@paulamillington4563]

on the question where you find the surface area when you have to work out the radius before, you did 4 pi not 4 x pi, when on the questions before you did 4 x pi? could you explain this?

4pi is the same as 4 x pi

[@garythehippopotamus9536]

They mean the same thing
