Answer:
642.39
Step-by-step explanation:
To get the increase,first get the given % of the amount and then add the result gotten to the amount
So, firstly
15% of 490
Make 15% a decimal by dividing it by 100
15/100 x 490
0.15 x 490 = 73.5
Increase = 490 + 73.5
= 563.5
Further so,
14% increase of 563.5
We do same as we did above
14/100 x 563.5
0.14 x 563.5 = 78.89
Therefore,
Increase = 563.5 + 78.89
= 642.39
Answer:
Surface Area = 2 ×22 /7 × 2 ×2 + 2 ×22 /7 ×2 × 14
= 176 / 7 + 1232 /7
= 176 / 7 + 176
= 352 / 7
= 50.2857
