Question:
The height of a cone is 15cm. If its volume is 1570cm³, find the radius of the base.
Solution:
h=15cm, volume=1570cm³
Let radius be r
1570=1/3×3.14×r²×15
r=√(1570/(15×3.14×1/3))
r=√(1570/(5×3.14))
r=√(100)
r=10cm
h=15cm, volume=1570cm³
Let radius be r
1570=1/3×3.14×r²×15
r=√(1570/(15×3.14×1/3))
r=√(1570/(5×3.14))
r=√(100)
r=10cm
