Find the lateral area of the cone in terms of pi. Radius 3cm, height 4

Lateral area of the cone = 15 π sq. cm

Step-by-step explanation:

Lateral area of the cone A = πr √(h²+ r²)

Here h = 4 cm and r = 3 cm

Plugin the values we will get the lateral area as,

A = π × 3 ×√(4² +3²)

  =  π × 3 ×√(16 +9)

 = π × 3 ×√(25)

 =  π × 3 × 5

  = 15 π sq. cm
