Answer:
11 sq.ft
Step-by-step explanation:
∅= 80×π/180= 4π/9
area= 1/2 × r²× ∅
= 1/2 × 16 × ∅
= 8∅
=8×(4π/9)
= 32π/9
= 11.17 ~11
Answer is 8%
(0.40)*(0.20) = 0.08 multiply by 100 to determine percent = 8% of the class are girls who wear glasses
estimate = (40 * 50) / (4 * 5)
= 2000 / 20 = 100 (answer)
Hey!
It's reduction because the square becomes smaller, and that happens when reducing.
One side of the larger square is 4. The same side on the smaller square is 2. When it's reduction, the answer is less than 1. It will be 1/2 because 2 is 1/2 of 4.
That means your answer is d.
