Question

Find the curved surface area volume and tsa of a cone having base radius 35cm and height 12cm

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Curved surface area of cone = 4070 sq.cm.

Total surface area of cone =  7920 sq.cm.

Volume of cone =15400 cubic cm

Step-by-step explanation:

Radius of cone = 35 cm

Height of cone = 12 cm

Curved surface area of cone = $\pi r \sqrt{h^2+r^2}=\frac{22}{7} \times 35 \times \sqrt{35^2+12^2}=4070 cm^2$

Total surface area of cone = $\pi r \sqrt{h^2+r^2}+\pi r^2 =\frac{22}{7} \times 35 \times \sqrt{35^2+12^2}+\frac{22}{7} \times 35^2=7920 cm^2$

Volume of cone =$\frac{1}{3} \pi r^2 h = \frac{1}{3} \times \frac{22}{7} \times 35^2 \times 12=15400 cm^3$
