Question

Q. 6. Curved surface area of a cone is 308 cm and its slant height is 14 cm.
Find:
(a) radius of the base​

Answer 1

$\sf{Answer}$

Step by step explanation:-

Given :-

CSA Of Cone is 308 cm²

Slant height is 14cm

To find :-

Radius of base

Formula:-

CSA Of Cone = πrl

Solution :-

πrl = 308m

$\sf\dfrac{22}{7}$ × r × 14cm = 308cm²

22 × 2 × r = 308

44 r = 308cm

r = $\sf\dfrac{308}{44}$ cm

r = 7 cm

So, Radius of base is 7cm

Answer 2

CSA of cone = 308

πrl = 308

22/7×r×14 = 308

22×r×2=308

44r = 308

r = 308/44

r = 7
