3. The roof of a castle tower is shaped like a cone. The base of the cone is 20 m across, and the height is 25 m. The slant height of the roof, which is unknown, is the hypotonuse of the right triangle formed with the radius
and the height of the cone. Show all your work!
(a) Sketch the roof of the castle tower. Label tho known lengths as described and label the unknown
length as x
(b) What is the slant height of the roof to the nearest whole number?

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!
