A bowl of fruit contains only strawberries and grapes. For every 2 strawberries in a bowl there are 5 grapes.

sdas [7]

Answer:

See Explanation

Step-by-step explanation:

Given

Let:

$S \to$ Strawberry

$G \to$ Grape

The given parameter can be represented as:

$S : G = 2 : 5$

Required

The question is incomplete as what is required is not stated.

Possible questions could be to determine the number of strawberries given a certain number of grapes, and vice versa

Take for instance

Calculate the number of grapes when there are 20 strawberries

We have:

$S : G = 2 : 5$

This becomes

$20 : G = 2 : 5$

Express as fraction

$\frac{20}{ G} = \frac{2 }{5}$

Make G the subject

$G = 20 * \frac{5}{2}$

$G = 10 * 5$

$G = 50$

<em>i.e. 50 grapes</em>

<em>Apply the same method given a certain number of grapes</em>

Describe the relationship between the area of a circle and its circumstances

valentina_108 [34]

Answer:

$A = \frac{r}{2}C$

Step-by-step explanation:

Given

Shape: Circle

Required

The area and the circumference (relationship)

This implies that, we write an expression that relates the area and the circumference.

Circumference is calculated as:

$C = 2\pi r$

Area is calculated as:

$A = \pi r^2$

The area can be rewritten as:

$A = \frac{2\pi r^2}{2}$

Further rewrite as:

$A = \frac{r}{2}*2\pi r$

Recall that: $C = 2\pi r$

So, the expression becomes

$A = \frac{r}{2}*C$

$A = \frac{r}{2}C$
