The semicircle shown is folded to form a right circular cone so that the arc PQ becomes the circumference of the base. Given that the diameter of the semicircle, PQ, is 10 cm, find
(i) the diameter of the base,
(ii) the curved surface area of the cone.

  1. Step-by-step explanation:

    photosynthesis the process by which green plants and other organisms transform light energy into chemical energy. Durning photosynthesis in green plants, light energy is captured, and use convert water ,carbon dio- oxide and Minerals into oxygen and energy rich organic compounds .

    Hope it is helpful.

  2. Answer:

    You can put this solution

    The arc PQ forms the circumference of the circlular base of the cone.

    The circumference (C) of a circle is given by:

    C+=+%28pi%29D Where D is the diameter and C+=+10cm. Solve this for D:

    10+=+%28pi%29D Solve for D.

    D+=+10%2Fpi
