Best ResponseYou've already chosen the best response.2a diameter is twice the radius... so diameter is 2 x r \(\Large V = \pi \times r^2 \times h \) V = 175pi h = 7 pi =3.1415.... now solve for r then double it

Best ResponseYou've already chosen the best response.0So would you divide everything over the the 175?

Best ResponseYou've already chosen the best response.2\(\Large V=π×r^2×h\) \(\Large 175\pi=π×r^2×7\) so first... divide both sides by pi then divide both sides by 7 then you should be left with r^2 = ... a number then sqrt both sides and you should be left with r then double it... and that = d
