Question

whats the area of a quarter-circle with diameter of 4 meters

Answer 1

90/360 * pi *2^2

Answer 2

as radius is half of diameter
solve it!

Answer 3

You are looking for this area.

Answer 4

im confused

Answer 5

so the formula for a full circle is A = pi r²
so if we have a quarter all we need is 1/4 of that
so we just do A = 1/4 pi r²

we have 4m for the diameter and the radius is 1/2 that or 2
so we plug in 2 into r
A = 1/4 pi 2^2
A = 1/4 pi 4

now we get 1/4 of 4 so we end up with 1
A = 1pi m^2

Answer 6

pi is equal to 3.14 so we can just say
A = 3.14 m^2
