Answer:this item, we are given with the radius equal to 22 cm.
In this measurement of the radius is the hypotenuse of the 30°-60°-90° triangle formed with the half the measurement of the side of the equilateral triangle being opposite to the 60° and equal to the hypotenuse times (1/2)(√3)
Step-by-step explanation:
If we let s be the side of the triangle then,
s/2 = r(1/2)(√3)
Multiplying the equation by 2,
s = r√3
Substituting,
s = (22 cm)(√3) = 22√3
The area of the equilateral triangle is computed through the equation,
A = (√3 / 4)(s²)
Substituting,
A = (√3 / 4)(22√3)² = 628.7 cm²
Therefore, the answer to this item is the first choice.
Answer:
504
Step-by-step explanation:
We are solving for the left leaning poll
Total voters = 900 + 1100
= 2000
Number of voters who say trump was responsible = 56percent x 2000
= 1120
Number of those who say otherwise = 44% x 2000
= 880
For this network
Those who say trump is responsible = 1120 x900/2000
= 1008000/2000
= 504 registered voters
