3) The radius of circle is 11 miles. What is the area of a sector bounded by a<br> 300° arc?
suter [353]

Answer:

Area = 316.6 mi^2

Step-by-step explanation:

Given:

Angle of arc = 300°

Radius of circle = 11 miles

Take π as 3.14

Required:

Area of the major sector

Solution:

Area of sector is given as: angle of arc/360*πr²

Thus,

Area = \frac{300}{360}*3.14*11^2

Area = 316.616667

Area = 316.6 mi^2 (rounded to the nearest tenth)

Brian's kite is flying above a field at the end of a 68m string.If the angle of elevation to the kite measures 70 degrees,how hi
Dvinal [7]

Answer:

h = 63.92\ m

Step-by-step explanation:

Given:

Angle of elevation = 70°

Length of string = 68 m

We need to find the height of the kite.

Solution:

Requirement figure attached in file.

Where:

BC = 68 m

AC = h (Height of the kite)

∠ABC = 70°

Using Cosine rule to find the height of the kite.

AC = BC\times sin(70)

h = 68\times 0.94

h = 63.92\ m

Therefore, height of the kite from Brian's head h = 63.92\ m.
