Answer:

The amount of frequent flyer miles Adam will receive if he takes the connecting flight rather than the direct flight = 107.34 miles

Step-by-step explanation:

The sketch of Adam's journey from city B through C and then A is shown in the attached image to.this question.

Using Sine rule, we can obtain the unknown distances BC and CA

In sine rule notation,

BA = c = 456.2 miles

BC = a = ?

CA = b = ?

Angle A = 41.7°

Angle B = 30.9°

Angle C = 107.4°

Sin rule is that

[(Sin A)/a] = [(Sin B)/b] = [(Sin C)/c]

[(Sin A)/a] = [(Sin C)/c]

(Sin 41.7°)/a = (Sin 107.4°)/456.2

a = 456.2 × (Sin 41.7°) ÷ (Sin 107.4°)

a = 318.03 miles

[(Sin B)/b] = [(Sin C)/c]

(Sin 30.9°)/b = (Sin 107.4°)/456.2

b = 456.2 × (Sin 30.9°) ÷ (Sin 107.4°)

b = 245.51 miles

Hence,

BC = 318.03 miles

CA = 245.51 miles

Total flyer miles covered by taking the connecting flight = 318.03 + 245.51 = 563.54 miles.

The difference between the total miles covered by taking the connecting flight and by taking the direct flight = 563.54 - 456.2 = 107.34 miles.

Hope this Helps!!!

Given:

radius = 30 cm

π = 3.14

Find: Area of the top surface of a circular manhole cover.

Area of a circle = π r²

Area of a circle = 3.14 * (30cm)²

= 3.14 * 900 cm²

**Area of a circle = 2,826 cm²**

The area of the top surface of a circular manhole cover is 2,826 cm²

**Best Answer:**<span>** ** </span><span>Using a calculator, it's easy to get the answer of 0.82602 cm^2.

When it says "proper number of significant figures", that just means the accuracy of the answer can only be equal to the accuracy of the original data. So since 0.234 and 3.53 are both only accurate to 3 s.f. the answer must also be accurate to 3 s.f.

**So the final answer you get is 0.826 cm^2.**</span>
