Question

Calculate the amount of ice-cream that can be put into a cone with base radius 3.5 cm and height 12 cm.​

Answer 1

Answer:

formula of vol. of cone = 1/3pie r²h

radius= 3.5cm

height = 12cm

now put the values

1/3×22/7×3.5×3.5×12

1/3×22/7×35/10×35/10×12

154cm³Answer ....

Answer 2

Answer :

Given :

• Base radius of cone = 3.5 cm

• Height of Cone = 12 cm

To Find :

Amount of ice-cream that can be put into a cone, That means we have to find the volume of the cone.

Formula To Find Volume :

${\boxed{\underline{\bf{Volume \: of \: Cone \: = \frac{1}{3} \: \pi \: {r}^{2} \: h}}}}$

where,

• r = radius

• h = height

Solution :

r = 3.5 cm

h = 12 cm

$\sf \implies \: \frac{1}{3} \: \pi \: {r}^{2} \: h \: = \:volume$

$\sf \implies \: \frac{1}{3} \times 3.14 \times {3.5}^{2} \times 12$

$\implies \sf \: \frac{1}{3} \times 3.14 \times 3.5 \times 3.5 \times 12$

$\implies \sf \: \frac{1}{3} \times 3.14 \times 12.25 \times 12$

$\sf \implies \frac{1}{3} \times 3.14 \times 147$

$\sf \implies \: \frac{1}{3} \times 461.58$

$\bf \implies \: 153.86$

$\bf \implies \: 153.86 = 154$

$\therefore \sf \large Volume \: of \: Cone \: = 154 \: c {m}^{3}$

• The amount of ice cream can't be measured, until it's weight isn't given.
