since the sum of radius and height is 37
therefore let radius = r m
and height= (37-r) m
according to the question
2Πr(r+h)=1628sq.m
2Πr(37)=1628
74Πr=1628
(74*3.14)r = 1628
232.36r = 1628
r = 1628/232.36
r = 7 m approximately
Πr^2h = 3.14*7*7*(37-7)
volume = (22/7)*7*7*30
= 22*7*30=210*22=4620 cube m
therefore let radius = r m
and height= (37-r) m
according to the question
2Πr(r+h)=1628sq.m
2Πr(37)=1628
74Πr=1628
(74*3.14)r = 1628
232.36r = 1628
r = 1628/232.36
