Answer:

D: 109 cm

Step-by-step explanation:

The formula of circumference is

$\pi d$

Diameter =

$17.4 \times 2 = 34.8$

Hence, circumference =

$34.8 \times \pi = 109.32742...$

rounded of to 109.

Answer:

circumference of a circle = 109.272

so correct option is D. 109 cm

Step-by-step explanation:

given data

circle radius = 17.4 cm

to find out

What is the circumference of the circle

solution

we will apply here formula for the circumference of a circle that is express as

circumference of a circle = π × d .........................1

here d is diameter of circle

and we know diameter = 2 × radius

put her value of radius we get diameter

so diameter d = 2 × 17.4 cm

diameter d = 34.8 cm

put these value in equation 1 we get

circumference of a circle = 3.14 × 34.8

circumference of a circle = 109.272

so correct option is D. 109 cm

analyze the diagram below and complete the instructions that follow. find the value of x and the value of y

Answers:
x = 2√2 units
y = 2√6 units

Explanation:
The given diagram is a right-angled triangle. This means that the special trig functions can be applied.
These functions are as follows:
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent

For getting x and y, we can choose to either work with θ = 30 or θ = 60.
I will work with 30.

1- For x:
We have:
θ = 30
x is the opposite side to θ
4√2 is the hypotenuse
Therefore, we can apply the sine function as follows:
sin θ = opposite / hypotenuse
sin (30) = x / 4√2
x = sin (30) * 4√2
x = 2√2 units

2- For y:
We have:
θ = 30
x is the adjacent side to θ
4√2 is the hypotenuse
Therefore, we can apply the cosine function as follows:
cos θ = adjacent / hypotenuse
cos (30) = y / 4√2
y = cos (30) * 4√2
y = 2√6 units

Hope this helps :)

Devon is 30 years older than his son, Milan. The sum of both their ages is 48. Using the variables d and m to represent the ages

statuscvo [17]

Answer+Step-by-step explanation:

m = man's age

s = son's age

m=s+36

(m+8)=3*(s+8)

Resolves to: s=10, m=46

So the man is 46 (=10+36).

In 8 years, son is 18 (=10+8), man is 54 (=3*18 and 46+8), thank you.
