Find the diameter of a circle with a circumference of 28.26 centimeters .

9cm

Step-by-step explanation:

since diameter is twice of the radius of circle so you need radius to solve this.

as circumference is given here and the formula for calculating circumference of circle is c=2r so for radius it can be write as r=c/2. putting value of c and we get radius.

r=c/2 = 28.26/2*3.147 = 4.5cm. now diameter is twice the radius i.e. 4.5*2=9cm.

the answer is 0.071

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
