Question

The curved surface area of a cone is 2200 sq.cm and its slant height is 50 cm . find the total surface area of cone (r_22/7)

Answer 1

Answer:

Step-by-step explanation:

Answer 2

The Total surface area of cone is 2816 sq.cm.

Step-by-step explanation:

Curved surface area of cone =$\pi r l$

Where r = radius , l = slant height

Slant height = 50 cm

The curved surface area of a cone is 2200 sq.cm

So,$\pi r (50)=2200$

$\frac{22}{7} \times r \times 50 = 2200$

$r = \frac{2200 \times 7}{22 \times 50}$

r=14 cm

Total surface area of cone =$\pi r l +\pi r ^2 =\frac{22}{7} \times (14)(50)+\frac{22}{7} \times (14)^2=2816 cm^2$

Hence The Total surface area of cone is 2816 sq.cm.
