1 Calculate the volume (in cubic cm) of a rectangular cylinder with height 0.5 metre
length 90 mm and breadth 20 cm​

9000 cm³

Step-by-step explanation: 0.50 m = 50 cm. 90 mm = 9 cm

If all sides are in right angle, volume is 50·9·20 cm³

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
