Answer:

62.8 square inches

Step-by-step explanation:

we know that

To find out how many square inches of space the rolling pin comes in contact with after one complete roll, determine the lateral area of the rolling pin

The lateral area of a cylinder is given by the formula

LA=\pi Dh

we have

D=2\ in\\h=10\ in\\\pi=3.14

substitute

LA=3.14(2)(10)=62.8\ in^2

The point (3 , k) is a distance of 5 units from (0 , 1). Find the two possible values of k.
valkas [14]
D =√(x2-x1)^2 + (y2-y1)^2
......._____________
5 =√(3-0)^2 + (k-1)^2
.......__________
5 =√3^2 + (k-1)^2

25 = 9 + (k-1)^2

16 = k^2 - 2k + 1

k^2 -2k - 15 = 0

(k - 5)(k + 3) = 0

k - 5 = 0.....or.......(k + 3) = 0

k = 5.........or.......k = -3

A number doubled and has four added to it. The result is divided by three and then added to the product of the original number a
IrinaK [193]
X= a number

(2x+4)/3 + (x+2)= 20
Multiply everything by 3 to eliminate the fraction
(3/1)((2x+4)/3) + (3)(x+2)= (3)(20)
2x+4+3x+6= 60
5x+10=60
Subtract 10 from both sides
5x=50
divide both sides by 5
x=10

Check:
Substitute answer in original equation
(2x+4)/3 + (x+2)= 20
(2(10)+4)/3+(10+2)= 20
(20+4)/3+12= 20
24/3+12= 20
8+12= 20
20=20

Hope this helps! :)
