A storage silo is in the shape of a cylinder with a hemisphere at the top. The total height of the silo is 35 ft. The circumference of the cylinder is 22 ft. Find the radius of the silo. Hint: You can find the radius of a circle when given the circumference. Use C = 2r and solve for r. r =  FORMTEXT      ft. Show your work below Find the height of the cylindrical portion of the silo. Hint: Now that you know the radius of the hemisphere, you can find the height of the cylinder, by Total Height of Silo  Height of Hemisphere h =  FORMTEXT      ft. Show your work below Find the volume of the cylindrical portion of the silo. Hint: Use the formula for the volume of a cylinder V =  FORMTEXT      ft.3 Show your work below   "$&024>@BVXZdfvxzݞ݋xtlah$hTCJ(aJ(hVCJ(aJ(hH$j\hjhjB* Uphp$jhjhjB* Uphp$jthjhjB* Uphph)jhjhjB* UmHnHphpu$jhjhjB* UphphjhjB* phpjhjhjB* UphphjhT&4hL  * f 6 n ( H^gdH8^8gd\^gd\^gd#M & Fgd\gd\ & Fgd\gdHgdTJ L l  ( * f 6 > @ T V X b d l n ̻̳vd\N@hHh\5>*CJaJhHhH5>*CJaJhHCJaJ#jh\B* UmHnHphpu$jhjh\B* Uphphjh\B* phpjhjh\B* Uphph#Mh#MB*CJaJphh\CJaJ!h\h\0JB*CJaJphh\0JB*CJaJph hHhHhHhH5CJaJhTCJ(aJ(h$h$CJ(aJ( ( HPRfhjtv8"*,@ɾə|ɾiə`^|ɾUh\CJH*aJ$jhjh\B* UphphHhHB* CJaJphphHhH5>*CJaJ#jh\B* UmHnHphpu$jDhjh\B* Uphphjh\B* phpjhjh\B* Uphph#Mh#MB*CJaJphh\CJaJhHh\B* CJaJphp!8"Z8pgd#Mgd\8^8gd\^gdH^gd\^gd#M & Fgd\^gd\8^8gdH Find the volume of the hemispherical portion of the silo.
