Answer:

1) The slant height = 9.8 cm ⇒ (C)

2) The slant height = 11.4 cm ⇒ (D)

Step-by-step explanation:

1) ∵ The slant height of the cone = √[(radius)² + (height)²]

∵ Diameter = 8 cm

∴ Radius = 4 cm

∵ Height = 9 cm

∴ Slant height = √(4² + 9²) = √97 = 9.8 cm ⇒ (C)

2) ∵ The slant height of the cone = √[(radius)² + (height)²]

∵ Diameter = 18 cm

∴ Radius = 9 cm

∵ Height = 7 cm

∴ Slant height = √(9² + 7²) = √130 = 11.4 cm ⇒ (D)

A^2 - 6a/a-6 • a+3/a
a(a - 6)/(a - 6) • a+3/a
a • (a + 3)/a
a(a+3)/a
a+3.

The correct solution to this question would be B. a+3.
