Question

C.S.A of cone 7150cm2 radius is 35cm find slant height prependicular height​

Answer 1

Answer:

hello

here is your answer,

here, csa of cone = 7150 cm2

radius of cone = 35cm

now, csa of cone = πrl

7150 = 22/7× 35 × l

7150×7/22×35 = l

65cm = l

thus, slant height of cone is 65cm.

now height of cone = √ L2-R2

h = √ 65^2-35^2

h = √3000

h = 54.78vm
