The radius of this right circular cone is 6 cm and the slant height is 10 cm. Which equation represents SA, the surface area of this cone?

Sagot :

Step-by-step explanation:

  • The surface area (SA) of a right circular cone is given by:
  • SA = πr(r + l)
  • where r is the radius and l is the slant height.
  • Given:
  • r = 6 cm
  • l = 10 cm
  • Substituting the values, we get:
  • SA = π(6)(6 + 10)
  • = π(6)(16)
  • = 96π
  • So, the equation representing the surface area of this cone is:
  • SA = 96π
  • To find the numerical value, multiply 96 by the value of π (approximately 3.14):
  • SA ≈ 96 × 3.14
  • ≈ 301.44 sq cm
