Answer 1

Answer:

103sq cm

Step-by-step explanation:

Area of cone=1/3*π*r*r*h

=1/3*3.14*3*3*11

=102.96cm2

=103cm2

Answer 2

Answer:

$\huge{\underline{\red{\rm{AnswEr:}}}}$

GIVEN :

Height of Cone = 11 cm

Radius of Cone = 3 cm

To Find :

Volume of Cone in Inches

Formula Used :

$vol = \frac{1}{3} \pi {r}^{2} h$

Proof :

Height of Cone = 11 cm

= 11 × 0.393

= 4.32 in

Radius of Cone = 3 cm

= 3 × 0.393

= 1.17 in

$vol = \frac{1}{3} \pi {r}^{2} h \\ = \frac{1}{3} \times 3.14 \times (1.17) {}^{2} \times 4.32 \\ = 6.189 \: {inch}^{3}$
