Find the circumference of the circle. Round your answer to the nearest hundredthin the center of the circle is 4.5 ft.
a 14.14
b 15.90
c 16.82
d 17.43

Answers

Answer 1
Answer:

Answer:

a. 14.14 ft²

Step-by-step explanation:

The measurement given refers to the diameter of the circle. The formula for the circumference and area uses the radius of a circle, therefore it is always safer to use radius instead of diameter

The radius is half of the diameter, which is 2.25 ft.

A=2*r*\pi \nA=2*2.25*\pi \nA=14.14ft^(2)
Answer 2
Answer: 2* π *radius

or 

π*diameter

What is the length of the hypotenuse, x, if (12, 35, x) is a Pythagorean triple?
​

Answers

Answer:

x = 37

Step-by-step explanation:

Lets take  12 as base (b) and 35 as perpendicular (p)

The hypotenuse (h) = x = ?

We know by using Pythagoras theorem

h^(2) =p^(2) +b^(2)

h^(2) =35^(2) +12 ^(2)

h^(2) = 1225 + 144\nh^(2)= 1369

h =√(1369)

Therefore h = 37

A game spinner has regions that are numbered 1 through 8. if the spinner is used twice, what is the probability that the first number is a 3 and the second is a 6? a. 116 b. 164 c. 964 d. 23

Answers

The probability that the first number is a 3 and the second is a 6 is 1/64

What is probability?

It is a branch of mathematics that deals with the occurrence of a random event.

Given:

spinner had region numbered from 1 to 8

So, the probability on the spinner has an equally likely chance of being selected = 1/8.

P(3) = 1/8

P(6) = 1/8

Thus, probability that the first number is a 3 and the second is a 6

= (1/8) × (1/8)

= 1/64
