The surface area of a cone can be calculated using the formula:
A = πr(r + l)
where r is the radius and l is the slant height.
Plugging in the values, we get:
A = 3.14(10)(10 + 15)
A = 3.14(10)(25)
A = 3.14(250)
A = 785
So the surface area of the cone is 785 square inches.
Answer: 785 square inches
A = πr(r + l)
where r is the radius and l is the slant height.
Plugging in the values, we get:
A = 3.14(10)(10 + 15)
A = 3.14(10)(25)
A = 3.14(250)
A = 785
So the surface area of the cone is 785 square inches.

The surface area of a cone can be calculated using the formula:
A = πr(r + l)
where r is the radius and l is the slant height.
In this case, we are given the hypotenuse (l) as 22 centimeters.
To find the radius, we can use the half of the base diameter, which is 25 centimeters.
r = 25/2 = 12.5 centimeters
Plugging in the values, we get:
A = 3.14(12.5)(12.5 + 22)
A = 3.14(12.5)(34.5)
A = 3.14(431.25)
A = 1,354.125
So the surface area of the cone is 1,354.125 square centimeters.
Answer: 1,354.125 square centimeters
A = πr(r + l)
where r is the radius and l is the slant height.
In this case, we are given the hypotenuse (l) as 22 centimeters.

r = 25/2 = 12.5 centimeters
Plugging in the values, we get:
A = 3.14(12.5)(12.5 + 22)
A = 3.14(12.5)(34.5)
A = 3.14(431.25)
A = 1,354.125
So the surface area of the cone is 1,354.125 square centimeters.

The surface area of a cone can be calculated using the formula:
A = πr(r + l)
where r is the radius and l is the slant height.
In this case, the radius is given as 6 centimeters, and the slant height is given as 18 centimeters.
Plugging in the values, we get:
A = 3.14(6)(6 + 18)
A = 3.14(6)(24)
A = 3.14(144)
A = 452.16
So the surface area of the spyglass is 452.16 square centimeters.
