Question

aJocker cap is in the form of right circular cone of base radius 7cm and height 27cm. find the area of the sheet required to make 10 such caps.

Answer 1

because the cap is in the form of right circular cone that's why here we use CSA of cone because its bottom is hollow.so to find CSA we also need slant height.to find it we use the formula that we use to find salnt height.
slant height will be 26....so at last we can find CSA and then to find the CSA of ten such cap CSA × 10 caps...
