Question

One question for a medal

Answer 1

you are told that it is ONE QUARTER of a circle


What is the formula for the area of the WHOLE circle?

Answer 2

A=1/4 pi radius squared

Answer 3

well - that is the area of the QUARTER as required

so radius = 5

just put that into your equation to get the answer (remember to round to nearest tenth like the question asks...)

Answer 4

how would i write that in a sentence

Answer 5

It asks you to write the formula (which you already did)

now use the formula to work out the area

Answer 6

ok

Answer 7

thanks

Answer 8

I suppose the first part could be

" find the area of the whole circle that hass the same radius as the quadrant, using A= pi r ^2 , then divide it by 4"

Answer 9

ok i already wrote my answer thank you
