Short Answer TypeThe circumference of the base of a 10 m high conical tent is 44 m. Calculate the length of the canvas used in making the tent if width of the canvas is 2 m.
Let the base radius of the conical tent be r m. Then,
= Area of the canvas used
∴ Length of the canvas used
= 11 x 12.2 m = 134.2 m
= 3.14)
A com cob, shaped somewhat like a cone, has the radius of its broadest end as 2.1 cm and length (height) as 20 cm. If each 1 cm2 of the surface of the cob carries an average of four grains, find how many grains you would find on the entire cob.
