Answer:
7.7 square metres or 7.669 square metres of metal sheet
Step-by-step explanation:
Volume of cylinder = 2×22/7×r×100cm
15.4 litres = 15,400 cm cube
Radius = 15 400×7/22 × 50
= 98cm
Surface area of cylinder = (2×22/7×49^2) + (2×22/7×49 × 100)
= 15 092 + 61 600
= 76 692 square cm
= 7.669 square metres of metal sheet required
44498.78 in²
A=2(1+2)a2=2·(1+2)·962≈44498.78 in²
B- enum and Dan bought 2 shirts
I am not sure
(2x-5)(x+6)=0
either 2x-5=0 Or, x+6=0
2x-5=0
2x=0+5
x=5/2
x+6=0
x=0-6
x=-6
so x=5/2 , x=-6
