Answer:
188.57
Step-by-step explanation:
i think i am right if i am right please give me a hart i am wrong please give me 1 star in rating
i think u take 8=l
but in csa
u have to take lateral surface area
6²+ 8²=10²
so 10
Given : The base radius of a cone is 6cm and the height is 8cm,
To Find : C.S.A
Solution:
C.S.A - Curved surface area
C.S.A of Cone = πRL
R = Base Radius of cone = 6 cm
L = Slant Height
L² = R² + h²
h = height of cone = 8 cm
=> L² = 6² + 8²
=> L² = 36 + 64
=> L² = 100
=> L = 10 cm
C.S.A of Cone = πRL
π = 3.14
R = 6 cm
L = 10 cm
=> C.S.A of Cone = (3.14)*6 * 10
= 188.4 cm²
