Answer 1

2,816 cm²

Step-by-step explanation:

The formula of finding Curved Surface Area of a cone is:

→ C.S.A of Cone = πrl

Here,

• CSA = 2200cm²
• π = 22/7
• l = Slant Height = 50 cm
• r = Radius of cone = ?

Finding the radius of cone:

→ C.S.A of Cone = πrl

→ 2200 = (22×50×r)/7

→ 2200 = (1100×r)/7

→ 2200×7 = 1100×r

→ 15400 = 1100×r

→ 15400/1100 = r

→ 14 = r

Hence, we know that the radius of cone is 14cm. Now, let us find the total surface area of the cone.

→ TSA of Cone = πr(l+r)

→ TSA of Cone = 22/7×14(50+14)

→ TSA of Cone = 22/7×14×64

→ TSA of Cone = 19712/7

→ TSA of Cone = 2816 cm²

Hence, the total surface area of the cone is 2,816 cm².
