Answer:1. 11,304 sq cm2. 11,304 sq cm3. A = 7128 cm4. A = 11405.76 cm2Step-by-step explanation:1. SA of sphere = 4 x pi x r squared= 4 x 3.14 x 30 x 302. length of base[a]=2.2mslant height [l]=1.9mTotal surface area=?we haveTotal surface area of a square pyramid :area of base+ curved surface area:a²+2al:2.2²+2*2.2*1.9:13.20 m²3.Formula:A = 2 (wl+hl+hw)GivenLength = 45cmWidth = 36cmHeight = 24cmSolution:A = 2 ((36×45)+(24×45)+(24×36))A = 2 (1620+1080+864)A = 2 (3564)A = 7128 cm---Can i get a brainliest?
