Answer:

176.715

Step-by-step explanation:

Area of circle: \pi r^{2}

To find the radius: diameter divided by 2

15/2=7.5

pi * 7.5 * 7.5 = 176.715

**I found my answer using the actual number for pi, if you're using 3.14 as pi then the answer is 176.625**

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>

An individual needs a daily supplement of at least 464 units of vitamin C and 252 of vitamin E and agrees to obtain this supplem
hichkok12 [17]

Answer:

z (min)  = 705

x₁  = 10

x₂  = 9

Step-by-step explanation:

Let´s call  x₁  quantity of food I ( in ou )  and x₂ quantity of food II ( in ou)

          units of vit. C   units of vit.E   Cholesterol by ou

x₁                 32                      9                         48

x₂                16                      18                          25

Objective function z

z  =   48*x₁   +  25*x₂        To minimize

Subject to:

1.-Total units of vit. C at least  464

32*x₁   +  16*x₂     ≥   464

2.- Total units of vit. E at least  252

9*x₁  + 18*x₂   ≥  252

3.- Quantity of ou per day

x₁   +   x₂   ≤  35

General constraints    x₁  ≥ 0    x₂   ≥ 0

Using the on-line simplex method solver (AtoZmaths) and after three iterations the solution is:

z (min)  = 705

x₁  = 10

x₂  = 9
