Solve the mathematics below and win MTN CARD: (1) A circular rubber ring has a radius of 14cm. If 16 of such rubber ring is placed on the top of each other to gain a height of 16cm. Find the area of the new shape. The last two missing digits of the card is AREA of the new shape minus 9789 CARD: 739832314031773 _ _ (2) 853701541644904_ _ THE MISSING DIGITS IS BETWEEN 15 T0 37 VERY GENUINE 2 Likes |

zoputa:are you sure you gave the right question? It will result in a negative answer. |

The new shape is a cylinder not a circle. Solve for the area of a cylinder. |

Xlyad: Considering the height, the new shape is now a cylinder. r=14, h=16 πr²h = 22/7*14²*16 = 22*2*14*16 =9,856cm² 9,856-9789==67 And=67 |

Apreecauts: And still the surface area |
Re: Solve Mathematics And Win MTN Card by ncpat(m): 4:10pm On Oct 10, 2020 |
uchaymart: The above formula is for volume and the hint was for the Area 1 Like

zoputa: Please be more explicit With the introduction of Height, the area can't be calculated any more because the stuff has changed from two dimensional to three dimensional; the only thing that can be calculated is the total surface area of the object formed. If we are to proceed to calculate the the total surface area, please note the the formula are different for a cylinder open at both ends, a cylinder closed at on end and a cylinder closed at both ends. However, I will chose 0.0616meters squared as my area if I should come across this question in the exams |
Re: Solve Mathematics And Win MTN Card by Xlyad(m): 11:49pm On Oct 10, 2020 |
uchaymart:that is wrong.what you calculated is the volume . The total surface area of a cylinder is a=2πr(r+h) i.e. the sum of the curved surface area and areas of the circular ends. 1 Like |
