What Is The Surface Area? How Did You Find It(filled-in Formula)?

Answers

Answer 1

Answer: 1719.22 mi squared

Step-by-step explanation:

you have to find the height first.

you only have r and hypotenuse

so

a^2 + b^2 = c^2

13^2 + b^2 = 29.1^2

169 + b^2 = 846.81

b^2 = 846.81 - 169

b^2 = 677.81

b = 26.03

height = 26.03

surface area formula :

          _______

πr(r+_/h^2+r^2)

                   ___________

π(13) [13 + _/26.03^2 + 13^2]

= 1719.22

Mark wants to make an enclosure for his cows.
He has 44 metres of fencing.
He wants the width to be 8 metres less than the length.
What dimensions should the field have?
?

Answers

Answer:

the length and width be 15 meters and 7 meters respectively

Step-by-step explanation:

The computation of the dimension of the field is given below;

Let us assume the fencing be p

Length be x

And, the width be x - 8

So,

P = 44

P = x - 8 + x - 8 + x + x

= 4x - 16

Now

4x - 16 = 44

4x = 44 + 16

4x = 60

x = 15

And, the width be 15 - 8 = 7

So, the length and width be 15 meters and 7 meters respectively

a certain coin is a circle with a diameter of 18mm. What is the exact area of either face of the coin in terms of pi (3.14)

Answers

Answer:

254.34 mm².

Step-by-step explanation:

For this problem, we use the formula to find the area of a circle, which is[tex]A=\pi r^2[/tex] . [tex]r[/tex] is the radius, which we can find by dividing the diameter by 2 and [tex]\pi[/tex] in this case is 3.14.

[tex]A=\pi r^2\\A=3.14*(18/2)^2\\A=3.14*9^2\\A=3.14*81\\A=254.34[/tex]

Therefore, the area of either face of the coin is 254.34 mm².

Two of the desserts are sugar/free. Three of the drinks are sugar-free. A meal deal combination is selected at random. Work out the probability that both the desserts and the drink are sugar free. Give your answer as a fraction

Answers

Answer: 8/15

Step-by-step explanation:

You need part a of the question to answer this question correctly. In part a of the question it is said there is 6 sandwiches, 3 desserts and 5 drinks.

Two of the desserts are sugar free (2/3).

Four of the drinks are sugar free (4/5)

Times these fractions together, 2/3x4/5= 8/15.

Hope this helps :)

The probability of selecting a sugar free dessert and drink is 2/5

Number of sandwiches = 6

Number of dessert = 3

Number of drinks = 5

Sugar free drinks = 3

Sugar free dessert = 2

Recall :

Probability = required outcome / Total possible outcomes

P(both dessert and drink are sugar free) :

(sugar free dessert) × p(sugar free drink)

(2 /3) × (3 / 5) = 6/15 = 2 / 5

Hence, the probability of selecting a sugar free dessert and drink is 2/5
