answer:
48in²
explanation:
Ok, so, it asks you to use the number 3 for pi instead of 3.14...(etc.) so keep that in mind.
π = pi (3 in this case)
r = radius (which is 4 in this question because 8 is the diameter and the radius is half of the diameter)
² = squared (e.g 2 x 2 is 2²)
first of all, write down the formula :-
A = πr²
then, substitute the numbers in :-
A = 3 x 4²
again, we use the number 3 for pi because the question has asked us to. If the question doesn’t ask you to use 3, you either use 3.14 or just click the pi button on your calculator.
Once you have put the equation into the calculator, you should get 48.
Hope this helps! if you are still struggling and need more help, feel free to message me and i will happily give you more examples.
