I don't get this question, can someone please explain it, thanks.
Heres the question: A lighthouse beacon can be seen 24 mi in all directions. What is the area over which the beacon can be seen?
- I think it's circumfrence, but I don't really know what to do.
Thanks, Bob.
The lighthouse beam is the radius of the circle. Since it can be seen for 24 miles, the radius is 24 miles.
The question asks for the area. To find the area of a circle we multiply:
A = pi * r^2
A = 3.14 * 24^2
A = 3.14 * 576
A = 1808.64 square miles
Thanks Ms. Sue, you help everyone on everything, your a big help!
You're very welcome, Bob. :-)
what is the volume of 12 in
10 in
5 in
3.14 x 24=75.36
What is 1

6 in a percent can you help me?
you rock!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
12x10x5=600 the volume Felix
Hi Bob!
No worries, I'm here to help you understand the question and how to approach it.
The question is asking about the area over which the lighthouse beacon can be seen. To find this area, we need to consider the shape that represents the region visible from the lighthouse. In this case, we assume that the lighthouse has a circular visibility pattern, where the light extends in all directions equally up to a certain distance.
To solve this, we need to determine the area of a circle with a radius of 24 miles. The formula for finding the area of a circle is:
Area = π * radius^2
In this case, the radius is given as 24 miles. So let's substitute this value into the formula:
Area = π * 24^2
To calculate the area, we need to know the value of π (pi). Pi is a mathematical constant that represents the ratio of a circle's circumference to its diameter. Since it is an irrational number, we usually approximate it to 3.14. So, let's go ahead and calculate the area:
Area = 3.14 * 24^2
Simplifying the equation:
Area = 3.14 * 576
Area ≈ 1809.44
So, the area over which the lighthouse beacon can be seen is approximately 1809.44 square miles.
