Can someone plz help me solve this for my winter recess assignment

B

Step-by-step explanation:

X is the number of hours, which for this question is 11.

So you do X × 8.9 --> 11 × 8.9 = 97.9

Y = 100 - 97.9

Y = 2.1

Therefore the answer is B

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
