 Question 40803: A hollow metal sphere has an internal radius of 20 cm and an external radius of 30 cm. Given that the density of the metal is 7.8 g/cm^3 (gramme per cm cube), find the weight of the sphere. (Take PI to be 3.14). Please help to solve this question. I have tried to calculate the volume of the sphere using the internal radius but then I'm stucked with what I needed to do with the external radius ? Thank you very much.

 Question 40804: It is a storage tank. So something must be inside it. So it will be hollow and it will have two radii (inner and outer). You have given only one diameter. So I presume that you have given inner diameter as the capacity is to be calculated and it cannot be calculated without knowing the inner diameter. Let the inner radius of the cylinder be 'r' metres. From your question it appears that the inner diameter of the hemispherical shell is also 'r' metres. Let the height of the cylindrical portion only be 'h' metres. Then h + r = 16.5 m But r = 4.7 m, so h = 16.5 - 4.7 = 11.8 m So volume of cylindrical portion = = = 818.9 . Also the volume of the hemispherical portion = = = 217.45 . Thus total capacity of the tank = 818.9 + 217.45 = 1036.35 . Click here to see answer by psbhowmick(529)

 Question 41448: A semicircle is folded to form a right circular cone so that its original base which measures 5 cm becomes the circumference of the cone base. Find :- a)The diameter of the base b)The curved surface area of the cone This is what I have done a)Diameter of the cone now = original base/2 = 5/2 = 2.5 b)Since the new diameter = 2.5 thus radius = diameter/2 = 2.5/2 = 1.25 Slant height = radius (is it correct ?) Curved surface are of the cone = PI r l (r = radius and l = slant length) = 3.142 x 1.25 x 1.25 = 4.909375 = 4.9 Click here to see answer by venugopalramana(3286)
