Correct Answer - Option 1 : 3850 cm

^{2}
**Given: **

Circumference of base of cap = 44 cm

Slant height of cap = 35 cm

**Formula Used:**

Curved surface area = πrl

Circumference of circle = 2πr

**Calculation:**

Circumference of the base of cap = Circumference of circle = 2πr

⇒ 44 = 2πr

⇒ r = 7 cm

Curved surface area = πrl

⇒ Curved surface area = 22/7 × 7 × 35

⇒ Curved surface area = 770 cm^{2}

Sheet required to make 1 cap = 770 cm^{2}

⇒ Sheet required to make 5 caps = 770 × 5 = 3850 cm^{2}

∴ 3850 cm^{2} sheet would be required to make 5 caps.

The correct option is 1 i.e. 3850 cm2
