Answer:

13.3

Step-by-step explanation:

shaded area = area of rectangle - area of semicircle.

5 inch = 12.7cm

6 inch = 15.24 cm

diameter = 12.7

radius = 12.7/2

= 6.35 cm

hence shaded area = (12.7 x 15.24) - (3.14 x 6.35 x 6.35 / 2)

= 193.548 - 63.306325

= 130.241675

= 130.24 (approx.)

A boat is anchored 2.2 km due south of a lighthouse. Along the shore, the town of Beachton is 16.8 km due east of the lighthouse

pogonyaev

Answer:

16.9 km

Step-by-step explanation:

From the diagram attached, we can see that the problem forms a triangle.

So, to find the distance(d) from the boat to Beachton , we can make use of Pythagoreas theorem.

Thus;

d² = 16.8² + 2.2²

d² = 282.24 + 4.84

d² = 287.08

d = √287.08

d = 16.9434

Approximating to the nearest tenth, we have;

d ≈ 16.9 km
