Answer:
5.25
Step-by-step explanation:
The light's coverage area is given mathematically as i.e. Area=
Given that a lighthouse casts a revolving beam of light as far as they peir and asked the area is covered.
The revolving beam of light covers the whole space i.e entirely 360°
I.e. it forms a circle-like region
Area of circle =
{ where r is the radius of circle}
Let's assume the distance traveled by light as "d"
as it forms a circular region, it forms a circle of radius "d"
Mathematical connection i.e. area of the region
⇒area of circular region=
{where d is the radius of region}

3600 * 1 * 0.085 = 306
answer: interest would be $306
Answer:
The angles are in the ratio of 2:3 and if you convert the ratio to units, the total units of the sum of the angles is 5 units. 5 units is thus equivalent to 90 and 1 unit is equivalent to 18. One angle is 2 units and hence is 36 degrees and the other angle is 3 units and hence is 54 degrees.
