CSA = 22/7 r s = 550
r s = 175
s^2 = r^2+h^2
r^2 (r^2+ 24^2) = 175 × 175
r^4 + 576 r^2 - 175* 175 = 0
r^2 = - 288 + sqrt[ 288^2+175^2]
= 337- 288 = 49
r = 7. cm.
Volume = 22/7 × 7^2 × 24 /3
= 1232 cm^3
r s = 175
s^2 = r^2+h^2
r^2 (r^2+ 24^2) = 175 × 175
r^4 + 576 r^2 - 175* 175 = 0
r^2 = - 288 + sqrt[ 288^2+175^2]
= 337- 288 = 49
r = 7. cm.
Volume = 22/7 × 7^2 × 24 /3
= 1232 cm^3
