Answer 1

Answer:

56.52 sq. cm

Step-by-step explanation:

Let radius and height be 5x & 12x

Volume of cone= 1/3(πrsq. h)

314= 1/3(3.14*5x*5x*12x)

(314*3)/3.14 = 300x cube

300x cube = 300

x cube = 1

x = 1

there fore, radius = 5 & height =12

l= √5 sq + 12 sq

√ 169 = 13

T. S. A of right circular cone = π(r+l)

= 3.14(5+13)

= 3.14(18)= 56.52 sweet. cm
