Answer:
True
Step-by-step explanation:
The sum of cubes a^ 3 + b^ 3 = (a + b) (a ^2 − a b + b^ 2 )
We need to determine if 216x^3 is a cube and 64 is a cube
216 = 6*6*6
216 x^3 = (6x) ^3
and 64 = 4*4*4 = 4^3
So 216x^3 +64 = (6x)^3 + 4^3
Answer: C = 53.3 inches
A = 226.1 inches²
Step-by-step explanation:
The inscribed square has equal sides. To determine the hypotenuse of the square which is also the diameter of the circle, we would apply the Pythagoras theorem which is expressed as
Hypotenuse² = opposite side² + adjacent side²
Hypotenuse² = 12² + 12² = 144 + 144 = 288
Hypotenuse = √288 = 16.97 inches
Radius = diameter/2 = 16.97/2 = 8.485 inches
The formula for determining the circumference of a circle is expressed as
Circumference = 2πr
Circumference = 2 × 3.14 × 8.485 = 53.3 inches
Area = πr²
Area = 3.14 × 8.485² = 226.1 inches²
The total weight of 4 dolls and 3 plush toys is 11 oz
Let's say the dolls weigh 2 oz and the plush toys weigh 1 oz
2-4= 8 1x3 =3
8+3=11
Then 2 dolls =4 and 3 plush toys= 3
Weight should be 7oz
Plus the weight of the box 1
Total= 8 not 10

Answer:
62.83
Step-by-step explanation:
Circumference=2 pi r
diameter=20
20*pi= about 62.83
so it sould be around 62.83
