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.
