# If the area of th

Given,

Area of the base of the right circular cone = 3850 cm2

Height of the right circular cone = 84 cm

Let the radius of the cone = r

And the slant height of the cone = l

As,

Area of the base of the cone = 3850 cm2

πr2 = 3850

227 × r2 = 3850

r2 = 3850 × 722

r2 = 1225

r = √1225

Therefore,

r = 35 cm

Now,

length = √h2 + r2

= √(84)2 + (35)2

= √7056 + 1225

= √8281

= 91 cm

So,

The slant height of the given cone is 91 cm.
