Answer:
____________________
Step-by-step explanation:
total surface = 6r² ⇔ 294=6r²
Then, r²=294÷6=49
Then r=√(49)=7
Therefore the volume = r³=7^(3)=343cm³.

Answer:
total surface area=6x^2
area=x^3
6x^2=294
x^2=294/6
x^2=49
x=SQR(49)
x=7
x^3=7^3
area=343
Answer:
Divide
30÷75%=40
Final Answer
40
Note: When finding answers like these divide the number by the percent.
Answer:
So 75% of 40 = 30.
Step-by-step explanation:
Hello!
Let's represent this as an equation so its easier to understand and solve.
We can represent any number as "n," and 75% as .
· n = 30
Multiplying by 100 to get rid of the fraction:
75n = 3000
Dividing by 75:
n = 40.
So 75% of 40 = 30.
The number is .
Hope this helps!
Answer:
0
Step-by-step explanation:
Using the algebraic expansion
x³ + y³ = (x + y)³ - 3xy(x + y)
Given
x³ + y³ - 12xy + 64
= (x + y)³ - 3xy(x + y) - 12xy + 64
Substitute x + y = - 4 into the expression
= (- 4)³ - 3xy(- 4) - 12xy + 64
= - 64 + 12xy - 12xy + 64
= 0
