Can someone solve these 3 questions

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

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!

a - base

b - exponent

so,

i would say b) is your answer

sorry if im wrong
