21.0 m²

mathstudent55 · Answer

Area of sector:
$$A = \frac{ n ^{o} }{ 360^{o} } \pi r ^{2}$$
where A = area
n = measure of central angle in degrees
r = radius of circle
Your diameter is 6.4 m, so the radius is 3.2 m.

10.24*(pi)*(37/72)

anonymous · Answer

is that all multiplied together to get the answer?

mathstudent55 · Answer

A = (185/360) x 3.14159 x (3.2)(3.2)

mathstudent55 · Answer

Multiply together: 185 x 3.14159 x 3.2 x 3.2 then divide by 360

i can't get that answer no matter how i type it in to my calculator :(

mathstudent55 · Answer

Type what I wrote above: 185 x 3.14 x 3.2 x 3.2 / 360

anonymous · Answer

i finally got it! thanks so much! my calculators online so i probably messed up while typing it in each time cause its pretty sensitive sorry i took so much of your time
