cone base area in shape of circle
area = 38.5cm
πr² = 38.5 cm
22/7 r² = 38.5 cm
r² = 38.5×7/22 cm
r² = 12.25 cm
r = √12.25 cm
r = 3.5 cm
l ---> slope height
h -----> height
r -----> radius
l ² = r² + h²
l² - r² = h²
l² - 12.25 = h²
√l²-12.25 = h
so height of the cone is √l²-12.25 cm
area = 38.5cm
πr² = 38.5 cm
22/7 r² = 38.5 cm
r² = 38.5×7/22 cm
r² = 12.25 cm
r = √12.25 cm
r = 3.5 cm
l ---> slope height
h -----> height
r -----> radius
l ² = r² + h²
l² - r² = h²
l² - 12.25 = h²
√l²-12.25 = h
so height of the cone is √l²-12.25 cm
