Question

Diameter of the base of a cone is 10.5 and it's slant height is 10 cm find its curved surface area​

Answer 1

Answer:

curved surface area=165 cmsquare

Step-by-step explanation:

curved surface area of cone =πrl

radius of the base of cone=10.5/2=5.25cm

slant height of cone=10cm

curved surface area of cone=

                                        (22/7 * 5.25 * 10)cm square

                                        (22/7 * 525/100)cm square

                                        (22 * 75/100 * 10)cm square

                                       

                                          =165cm square

Answer 2

Answer:

curved surface area of cone is 165cm.sq
