Question

Sam purchases a bowl. The diameter of the bowl is 14 cm. What is the circumference of the bowl? Use π as 3.14 *
-28cm
-43.96cm
-7cm

Answer 1

Answer:43.96cm

Step-by-step explanationDIAMETER = 14cm

RADIUS= 7cm

CIRCUMFERENCE OF THE BOWL= 2πr

= 2*3.14*7

=6.28*7

=43.96

Answer 2

Question :-

Sam purchased a bowl . The diameter of the bowl is 14 cm . What is the circumference of the bowl ? ( use π = 3.14 )

• Option A - 28 cm

• Option B - 43.96 cm

• option C - 7 cm

Answer :-

Given :-

The diameter of the bowl is 14 cm .

Required to find :-

• Circumference of the bowl ?

Formulae used :-

$\large{\leadsto{\boxed{\rm{ Radius = \dfrac{Diameter }{2}}}}}$

$\large{\leadsto{\boxed{\rm{ Perimeter \; of \; a \; circle = 2 \pi r }}}}$

Solution :-

Given that :-

Diameter of the bowl is 14 cm

He asked us to find the perimeter of the bowl .

So,

In order to find the perimeter of the bowl we should find the measurement of the radius .

Since, radius enables us to find the circumference of the bowl .

Hence, using the formula

$\large{\leadsto{\boxed{\rm{ Radius = \dfrac{Diameter }{2}}}}}$

So,

Substitute the required values

$\Rightarrow{\tt{ Radius = \dfrac{14}{2}}}$

$\implies{\red{\tt{ Radius = 7 \; cm }}}$

Hence,

Radius of the circle is 7 cm .

Now using the formula,

$\large{\leadsto{\boxed{\rm{ Perimeter \; of \; a \; circle = 2 \pi r }}}}$

So,

substitute the required values

$\longrightarrow{\tt{ Circumference = 2 \times \pi \times7 }}$

Since it is mentioned that pi value should be taken as 3.14 so now substitute this value

$\longrightarrow{\tt{ Circumference = 2 \times 3.14 \times 7 }}$

$\longrightarrow{\tt{ Circumference = 43.96 \; cm }}$

$\large{\leadsto{\boxed{\tt{ Circumference \; of \; the \; bowl = 43.96 \; cm }}}}$

Option - B is correct .

Additional Information :-

1. The diameter is twice the radius .

This represented as ,

Diameter = 2 x radius

2. Formula for finding the area of the circle is ;

$\large{\leadsto{\boxed{\rm{ Area \; of \; a \; circle = \pi {r}^{2 }}}}}$

3. The words perimeter and the circumference have the same meaning.

4. Refer to the attachment to understand about the radius and diameter clearly .
