The perimeter of a rectangle is twice the
masya89 [10]

Answer:

The length is 14 m.

Step-by-step explanation:

length = L

width = W

perimeter = P

"The perimeter of a rectangle is twice the  sum of its length and its width."

P = 2(L + W)

"The  perimeter is 40 meters"

40 = 2(L + W)

"and its length is 2  meters more than twice its width."

L = 2W + 2

Replace L with 2W + 2 in equation 40 = 2(L + W):

40 = 2(2W + 2 + W)

40 = 2(3W + 2)

20 = 3W + 2

3W = 18

W = 6

The width is 6 meters.

L = 2W + 2 = 2(6 m) + 2 m = 12 m + 2 m = 14 m

Answer: The length is 14 m.

A standard bowling ball cannot be more than 27 inches in circumference. What is the maximum volume of such a ball (to the neares
ddd [48]

Answer:

333 in^3

Step-by-step explanation:

Circumference = pi *d

27 = pi*d

Replacing d with 2*r  ( 2 times the radius)

27 = pi * 2 * r

Divide each side by 2

27/2 = pi *r

13.5 = pi *r

Divide by pi

13.5/ pi = r

We want to find the volume of a sphere

V = 4/3 pi * r^3

V = 4/3 pi (13.5/pi)^3

  = 4/3 pi * (13.5)^3 / (pi^3)

  4/3 pi/pi^3  * (13.5)^3

   4/3 * 1/ pi^2 *2460.375

 3280.5 / pi^2

Let pi be approximated by 3.14

 380.5/(3.14)^2

 332.7214086 in^3

To the nearest in^3

333 in^3
