Question

height of the cone us half of the radius and the volume of the cone is volume is sphere r=7 then space is
a. 14m b.14/√2 c.14×√2 d.none

Answer 1

Answer:

Step-by-step explanation:

volume of the sphere= (4/3)πr³

volume of cone =(1/3)πR²h

volume of cone =volume of sphere

(1/3)πR²h=(4/3)π7³............................(i)

but in cone  h=(1/2)R

put in eq (i)

(1/3)πR²(1/2)R = (4/3)π7³

R=14 cm

h=7cm
