AgentD12:A chord gotta be a straight line. Only an arc or the circumference of the full circle would pass through C from E to F. |

rickyboss333:I like ur Method; short, coincise, straight to d point.. But for the benefit of others and depending on the question, this method of mine below may come in handy.. |

Correction. insert unit. 32.18cm² (2 d.p) or 32.2cm² (3s.f) or 32cm²(since qtn parameters are in whole numbers) Like I said, @rickyboss333, mine is longer.. but geometric theorems can come in handy when data parameters are scarce... Also, Approximation varied our answers slightly in qtn 2. (36.87°≈ 37°) All the same, urs is more efficient.

chimex38:yea ur right, very true. its been pretty long I did those mensuration stuff and I can't remember those theorems otherwise I would have used ur method. I just had 2 use common sense and go straight from first principles. am glad they both came up to be dsame answer. means my head is still game (lol)  chimex38:yea ur right, very true. its been pretty long I did those mensuration stuff and I can't remember those theorems otherwise I would have used ur method.

rickyboss333:Thanks it better I have another question pls A doorway is made up of an arch, ABC, which is a quater of a circle of radius 2m, two uprights, CD and AE of height 3m, and a horizontal base a) show that the perimeter of the doorway, in metres, is ^(pie)+6+2root2 b)find a similar expression for the area of the doorway in terms of root2 and pie, simplifying ur answer as far as possible.[if required,take sin45=Cos45=1/root2

AgentD12:To be honest with u, at this stage am not sure if am doing u any good by solving these questions for u to simply copy. I guess they are assignments and assignments are meant to expose and challenge your understanding of the subject matter. I wish I was opportuned to have a one on one dealing with u, to explain and tutor u so that u could always help yourself and understand the subject better. I would advice u get a private tutor. please, i mean no offense 1 Like |
