Answer» I) 22/7*r^2*h = 308022/7*r^2*(h-5) = 2310r^2*h = 3080*7/22= 28022/7*r^2*h-22/7*r^2*522/7*280-22/7*r^2*5 = 231022/7(280-r^2*5) = 2310280-r^2*5 = 2310*7/22= 735-r^2*5 = 735-280= 455r^2 = 455/5= 91therefore r = root 91ii) r^2*h = 280h = 280/91therefore h = 3.07iii) height = 3.07/2csa + base area = 2*22/7*root 91*3.07/2+ 22/7*root 91^2= 295.64 root 91 cm^2 |
