Question

tent is of area 616 sq. cm. A 48cm long vertical pole is placed at its centre so that it touches the roof of the tent. How much canvas is needed to make the tent if the base is also covered with canvas? 1) 2816cm 2) 2861cm 3) 2618cm 4) 268 lom? 18. The probability if not getting 1 or 6 in a single toss of a ​

Answer 1

Answer:

2816cm square2

Here, we need to calculate the total surface area of the cone.

Total surface area of the cone = πr(l+r)

=πrl+πr square2

where πr square2 is the area of the base of the cone.

Given: πr square2=616cm square2

⇒22/7×r square2=616

⇒r square2=616×7/22=196cm square2

⇒r = 14 cm

Also, h = 48 cm

Now,

l=√h square2+r square2

=√48 square2+14square2

=√2304+196

=√2500

=50cm

So, T. S. A of conical tent

= πrl+πr square2

= 22/7×14×50+616

= 2816 cm square2
