what's the radius of a cone with a 12m and height 10 slant height
To find the radius of a cone, we can use the Pythagorean theorem, which relates the radius (r), height (h), and slant height (l) of a cone.
The Pythagorean theorem for a cone is given by:
r^2 + h^2 = l^2
Given:
Height (h) = 10 m
Slant height (l) = 12 m
Substituting the given values in the Pythagorean theorem equation:
r^2 + 10^2 = 12^2
r^2 + 100 = 144
r^2 = 144 - 100
r^2 = 44
Taking the square root of both sides to isolate r:
r = sqrt(44)
r ≈ 6.63
Therefore, the radius of the cone is approximately 6.63 meters.

Apologies for the incorrect response.
To find the radius of a cone, we can use the formula for the slant height:
l^2 = r^2 + h^2
Given:
Height (h) = 10 m
Slant height (l) = 12 m
Substituting the given values in the formula:
12^2 = r^2 + 10^2
144 = r^2 + 100
r^2 = 144 - 100
r^2 = 44
Taking the square root of both sides to isolate r:
r = sqrt(44)
r ≈ 6.63
Therefore, the radius of the cone is approximately 6.63 meters.
The point on a cone where two or more line segments meet is called the
The point on a cone where two or more line segments meet is called the vertex.
To find the radius of a cone, we need either the slant height or the height, and also the length of the lateral side. In this case, we have the height and the slant height.
The slant height is the distance from the tip of the cone to any point on the edge of the base. Let's call the slant height "s".
First, let's find the radius using the Pythagorean theorem. It states that in a right triangle, the square of the hypotenuse (in this case, the slant height) is equal to the sum of the squares of the other two sides.
So, we can write the equation as:
s^2 = r^2 + h^2
where r is the radius and h is the height.
In this case, we have s = 10 and h = 12.
Plugging in these values, we have:
10^2 = r^2 + 12^2
Simplifying further:
100 = r^2 + 144
Subtracting 144 from both sides:
100 - 144 = r^2
Simplifying:
-44 = r^2
To solve for r, we take the square root of both sides:
r = √(-44)
However, the square root of a negative number is not defined in the real number system. This means that there is no real solution for the radius in this case.
Hence, with the given information, we cannot determine the radius of the cone.
