Question

The curved surface of a cone is 2200 cm2. If
the radius of its base is 14 cm, calculate its
height​

Answer 1

Answer:

PLZ MARK AS BRAINLIEST !

Step-by-step explanation:

According to the question

curved surface of a cone =2200cm.  

and it's radius is 14 cm.  

curved surface of cone = 2πrh  

2200 cm.square = 2 × 22/7 × 14 × h  

2200 cm.sq.= 2 × 22 ×2 × h  

2200 cm.sq. = 88 × h  

h =2200/88  

h =25cm.

Answer 2

Answer:

48cm

Step-by-step explanation:

radius = 14cm

slant height = l

height = h

-----------------------

Curved surface area = πrl

2200cm2 = 22/7 × 14 × l

2200 × 7/22 × 1/14 = l

l = 50cm

So,

the slant height is 50 cm

Using Pythagoras theorem,

l^2 = r^2 + h^2

50^2 = 14^2 + h^2

2500 = 196 + h^2

2500 - 196 = h^2

2304 = h^2

√2304 = h

h = 48cm
