Area = π * r * r
49 = radius * radius
Radius = 7
Hope this helped☺☺
294 cm^2 = 6 * r^2 (the cube has 6 faces)
so the radius is 7 cm
the volume is 7^3 cm^3 = 343 cm^3
Draw a number line. Plot -1 on the number line and make this a filled in circle. Shade to the right of the filled in circle to indicate the set of values x such that 
So x could be -1 or it could be larger. The fact that x = -1 is possible is why we have a closed or filled in circle (instead of an open hole) at this endpoint.
Answer:
58 and 42.
Step-by-step explanation:
Let the 2 numbers be x and 100-x.
Also let x be the largest number, so
x ≥ 100 - x + 16 ( 'At least 16' means equal to 16 or greater than 16).
Add in x to both sides:
x + x ≥ 100 + 16
2x ≥ 116
x ≥ 58.
But since the sum of the 2 numbers is 100, x must be 58 and the other number is 42.
With replacement, each draw has a probability of
9 pink out of 18 total number of chips.
Therefore, by the multiplication rule, the probability of having both draws picking a pink is
P(pink,pink) = (9/18)*(9/18) = 81/324 [ = 1/4 ]
or
P(pink,pink) =
