The area of a circle, in terms of π, is 196π m2. Find the value of the radius.

AleksandrR [38]

Step-by-step explanation:

if area of circle = pi times radius^2,

area of circle divided by pi = radius^2

so, square root (area of circle divided by 2) = radius.

so, 196pi = m2

approx 616

616=m2

sqrt 616 =m

approx value of radius is 25 or 24.8

2x - 4y + 1z = 11 ⇒ 2x - 4y + 1z = 11
1x + 2y + 3z = 9 ⇒ 1x + 2y + 3z = 9
3x + 5z = 12 1x - 2y - 2z = 2
 1x - 2y - 2z = 2
2x - 4y + 1z = 11 -2x + 2y - 2z = -3
1x + 2y + 3z = 9 ⇒ 1x + 2y + 3z = 9 x - 4z = 1
3x + 5z = 12 ⇒ 3x + 5z = 12 x - 4z + 4z = 1 + 4z
 -2x + 2y - 2z = -3 x = 1 + 4z
 1 + 4z - 2y - 2z = 2
 1 - 2y + 4z - 2z = 2
 1 - 2y + 2z = 2
 - 1 - 1
 -2y + 2z = 1
 -2y + 2z - 2z = 1 - 2z
 -2y = 1 - 2z
 -2 -2
 y = -0.5 + z
 x + 2(-0.5 + z) - 2z = 2
 x - 1 + z - 2z + 2 = 2
 x - 1 + z = 2
 + 1 + 1
 x + z = 3
 x - x + z = 3 - x
 z = 3 - x

mrs. marks have 2/3 pound of cheese. she has 1/15 pound on each sandwich. how many sandwiches can she make with the cheese she h

Tema [17]

Answer:

Step-by-step explanation:

2/3 can be multiplied by 5 to equal 15ths since we can know 15 (seconds number fraction) is 5 times the originals (first numbers fractions)

This equals to 10/15 and means that with 1/15th on each 10 sandwiches can be made.

The answer gives it straight forward but explanation gets in depth

Edit: I saw your answer and yes it equals 10 but you multiply what it is a fraction of too.

2/3

10/15

Hope that helps some more
