Circular Cone Surface Area

  1. Lateral Surface Area = πrs = πr√(r2 + h2)
  2. Base Surface Area = πr2
  3. Total Surface Area
    = L + B = πrs + πr2 = πr(s + r) = πr(r + √(r2 + h2))

Capsule Surface Area

  1. Surface Area = 2πr(2r + a)

Circular Cylinder Surface Area

  1. Top Surface Area = πr2
  2. Bottom Surface Area = πr2
  3. Total Surface Area
    = L + T + B = 2πrh + 2(πr2) = 2πr(h+r)

Cube Surface Area

  1. Surface Area = 6a2

Conical Frustum Surface Area

  1. Lateral Surface Area
    = π(r1 + r2)s = π(r1 + r2)√((r1 - r2)2 + h2)
  2. Top Surface Area = πr12
  3. Base Surface Area = πr22
  4. Total Surface Area
    = π(r12 + r22 + (r1 * r2) * s)
    = π[ r12 + r22 + (r1 * r2) * √((r1 - r2)2 + h2) ]

Hemisphere Surface Area

  1. Curved Surface Area = 2πr2
  2. Base Surface Area = πr2
  3. Total Surface Area= (2πr2) + (πr2) = 3πr2

Rectangular Prism Surface Area

  1. Surface Area = 2(lw + lh + wh)

Pyramid Surface Area

  1. Lateral Surface Area = a√(a2 + 4h2)
  2. Base Surface Area = a2
  3. Total Surface Area
    = L + B = a2 + a√(a2 + 4h2))
    = a(a + √(a2 + 4h2))

Spherical Cap Surface Area

  1. Surface Area = 2πRh

Sphere Surface Area

  1. Surface Area = 4πr2

For example, To sphere when r = 3

  1. To calculate the surface area of a sphere, use the following formula: 4πr2. When you substitute r for its value, you get 4π * 32, which equals 113.09734 m2.

For example, To cone when r = 3, h = 3

  1. To calculate the surface area of a cone, use the following formula: πr(r + √(r2 + h2)). When you substitute r and h for their values, you get π3(3 + *radic;(32 + 32)), which equals 68.26028 m2.
