Question

Please help plsass….

Answer 1

D. none of the above

Explanation:

the area of a circle is

pi×r²

that is for the whole circle, which is the same as 360 degree arc.

now that we have only 254 out of the total of 360 degrees, the sector area is

pi×r² × 254/360

pi×9² × 254/360 = pi×9 × 254/40 = pi×57.15 =

= 179.5420202... cm²

rounding to 1/10 is 180.0 cm².

so, it is actually D - none of the above.
