Question

The diameters of two right circular cones are equal. If their slant heights
in the ratio 5:4, then the ratio of their curved surface areas is:
(a) 4:5
(b) 25:16
(c) 5:4
(d) 1:1​

Answer 1

Answer:

Answer is (c)

Step-by-step explanation:

curved surface area cone = πrl

those diameter are equal

therefore it's radius are equal

so it's right answer is option (c)
