circumference = 2PIr

20*2*3.14 = 40*3.14 = 125.6

The answer is A. 125.6

C = (2)(pi)(r)
So in this case, the circumference is 125.6 inches

What is the fraction to this picture?

lara31 [8.8K]

The fraction is 2/6
This is because there are 6 total sections in the shape (6 becomes denominator) and 2 colored in sections (2 becomes the numerator)

Pls help I don't understand:

sineoko [7]

Answer:

Part a) $T(d)=2d+30$

Part b) $T(6)=42\ minutes$

Step-by-step explanation:

Part a) Write an equation for T (d)

Let

d ----> the number of days

T ---> the time in minutes of the treadmill

we know that

The linear equation in slope intercept form is equal to

$T=md+b$

where

m is the slope or unit rate

b is the y-intercept or initial value

In this problem we have

The slope or unit rate is

$m=2\ \frac{minutes}{day}$

The y-intercept or initial value is

$b=30\ minutes$

substitute

$T(d)=2d+30$

Part b) Find T (6), the minutes he will spend on the treadmill on day 6

For d=6

substitute in the equation and solve for T

$T(6)=2(6)+30$

$T(6)=42\ minutes$
