Answer:
diameter [d]=15cm
radius [r]=7.5cm
slant height be l
and
height be h.
lateral surface area of cone =
πrl=477cm²
l=477/(3.1416*7.5)
l=20.244
now
h=[tex]\sqrt{20.2²-(7.5/2)²}=20cm[/tex]
height=20cm.
LSA of cone = πrl = 477cm²
L = 477/(3.1416 × 7.5)
L = 20.244
Height (h) = √{20.2²-(7.5/2)²}
h = 20cm
