l²=r²+h²
h²=l²-r²
h²=169-25
h=12
volume=1/3πr²h
volume=1/3×22/7×5×5×12
volume=314.25cm³
thank you
answer is approximate
ok so you want steps to solve the sum ok
1/3×22/7×5×5×12 ok so cancel 3 and 12
22/7×5×5×4 ok
now 5×5×4=100
2200/7 ok
divide it
314.28cm³ ok thanks

indresh834: which slant or normal
Ali7234: slant
shiva2210: for slant
indresh834: so calculate normal height and then put in formula
indresh834: ok
Ali7234: ok
Ali7234: thanks
indresh834: and if put slant height instead of normal height you wont get correct answer
shiva2210: we won't get correct answer
indresh834: yes
