On number 1, it is 5-2, not 2-5.
On number 2, 3(4+12).
On number 3, (15/3)+10
On number 4, 2+6*4
On number 5, it is correct
On number 6, 2(8-2)
On number 7, it is correct

Answer:

$2\frac{1}{3}\: ft$

Step-By-Step Explanation:

$Height\: of \:sail = 1\frac{1}{6}\: ft = \frac{7}{6}\: ft\\Base\: of \:sail = 4\: ft \\Area\: of \:sail =\frac{1}{2} \times base \times height\\=\frac{1}{2} \times \frac{7}{6} \times 4\\= \frac{7}{6} \times 2\\=\frac{7}{3}\\=2\frac{1}{3}\: ft$

Answer:

So we know the formula to calculate the area of the circular sector:

S=(r^2*π*a)/306°=

(5^2*3.14*40°)/360°= (1000*3.14) /360=8.72cm^2 so the right alternative should be the first one ,A.

Step-by-step explanation:

r - radius of the circle

a - corner of the circular sector

S - surface
