The circumference of a circle is 12 inches. What is the radius

1 answer:

7 0

Greetings!

"The circumference of a circle is 12 inches. What is the radius?"...

We can use the formula to find the circumference of circle to solve this:
 $2 \pi r$

Input the information we know:
 $2 \pi r=12$

Solve for r, using the properties of equality:

Simplify.
 $6.28r=12$
Divide both sides by 6.28
 $(6.28r)/6.28=(12)/6.28$ 
Simplify.
 $r=1.91$

The radius is 1.91cm long.

Hope this helps.

Question 3 Find the equation of the line joining (-2,4) and (3,7)

otez555 [7]

Answer:

y = (3/5)x+26/5 or 5y = 3x+26

Step-by-step explanation:

Applying,

The equation of a line in two point form

(y₂-y₁)/(x₂-x₁) = (y-y₁)/(x-x₁)............... Equation 1

From the question,

Given: y₂ = 7, y₁ = 4, x₂ = 3, x₁ = -2

Substitute these values into equation 1

(7-4)/[3-(-2)] = (y-4)/(x+2)

3/5 = (y-4)/(x+2)

5(y-4) = 3(x+2)

5y-20 = 3x+6

5y = 3x+6+20

5y = 3x+26

y = (3/5)x+26/5

Hence the equation of the line is y = (3/5)x+26/5 or 5y = 3x+26

Write and solve the system of linear equations described by the application and then answer the question. One hundred sixty feet

Lena [83]

Answer:

80 ft x 40 ft

Step-by-step explanation:

Let 'L' be the length of the longer side and 'W' be the length of the shorter side (or the width).

The equations that compose the linear system are:

$L+2W=160\\L=2W$

Solving the system:

$L+L=160\\L=80\\W=\frac{L}{2}\\W=40$

The garden is a rectangle with dimensions 80 ft x 40 ft.

F(x)=4x+1 and g(x)=x^2-5find(f-g)(x)

Vinvika [58]

Answer:

Step-by-step explanation:

Given f(x)=4x+1 and g(x)=x²-5

(f-g)(x) is derived by taking the difference of both functions

(f-g)(x) = f(x)-g(x)

(f-g)(x) = 4x+1 - (x²-5)

(f-g)(x) = 4x+1-x²+5

(f-g)(x) = -x²+4x +6

This gives the requires expression

Shawna climbed 5 flights of stairs. There were 9 steps in each flight. How many steps did Shawna climb?

exis [7]

Shawna will climb 45 steps

The first step is to write out the parameters given in the question

Shawna climbed 5 flights of stairs

There were 9 steps in each flight

The number of steps can be calculated by multiplying the number of flight of stairs by the number of steps

= 9 × 5

= 45

Hence there are 45 steps for Shawna to climb
