Answer

Formula

Circumference\ of\ circle = 2\pi r

where r is the radius of a circle.

As shown in the image

Diameter of the circle = 16 .3 cm

Radius\ of\ the\ circle = \frac{16.3}{2}

                                   = 8.15 cm

Put in the formula

Circumference\ of\ circle = 2\pi\times 8.15

As

\pi = 3.14

Circumference\ of\ circle = 2\times 3.14\times 8.15

                                                 = 51.2 cm (approx)

Therefore the circumference of a circle is 51.2cm (approx) .

Option (D) is correct .

The circumference of the circle \boxed{51.2{\text{ cm}}}. Option (D) is correct.

Further explanation:

The formula for the circumference of the circle can be expressed as follows,

\boxed{{\text{Circumference of circle}} = 2\pi r}

The formula for the area of the circle can be expressed as follows,

\boxed{{\text{Area of circle}} = \pi {r^2}}

Here, “r” represents the radius of the circle.

The relationship between the radius and the diameter can be given by,

\boxed{r =\dfrac{d}{2}}

Here, “d” represents the diameter of the circle.

Given:

The options are as follows.

A.102.4{\text{ cm}}

B.63.4{\text{ cm}}

C.25.6{\text{ cm}}

D.51.2{\text{ cm}}

Explanation:

The diameter of the circle is 16.3{\text{ cm}}.

The radius of the circle can be obtained as follows,

\begin{aligned}{\text{Radius}}&= \frac{{16.3}}{2}\\&= 8.15\\\end{aligned}

The radius of the circle is 8.15{\text{ cm}}.

The circumference of the circle can be obtained as follows,

\begin{aligned}{\text{Circumference of circle}}&= 2\times\frac{{22}}{7}\times 8.15\\&=\frac{{44}}{7}\times 8.15\\&= 51.2\\\end{aligned}

The circumference of the circle \boxed{51.2{\text{ cm}}}.Option (D) is correct.

Option (A) is not correct as the circumference of the circleis  .

Option (B) is not correct as the circumference of the circle is  .

Option (C) is not correct as the circumference of the circle is  .

Option (D) is correct as the circumference of the circle is  .

At the product store you can buy four bags of bananas for 2084 how much would it cost if you were to buy 3 bags
Darya [45]

Answer:

1563

Step-by-step explanation:

x= 1 bag of bananas

so, 4x=2084

Divide 2084 by 4 to find how much 1 bag of bananas would cost. 2084/4= 521.

To find how much 3 bags of bananas would cost, multiply 521 (the price of one bag) by 3. 521x3= 1563

3 bags of bananas are $1563
