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
