Area of a circle = pi r^2 = pi * 12^2 = 452.4 in^2 to nearest tenth.
Answer:
Step-by-step explanation:
If two values are inversely proportional, their product must be maintained. That way, if one value goes up, the other goes down by the same extent.
Therefore, if and vary inversely, their product will be the same for all values of and .
Let and as given in the problem. Substitute values:
Hence, the maintained product is .
Thus, we have the following equation:
Substitute to find the value of when :
Answer:
A=t+258
Step-by-step explanation:
Hello from MrBillDoesMath!
Answer:
Choice D, 81
Discussion:
By log 3x = 4 I presume that "3" is the base not a multiplier of x. Assuming it is the base, then the equation is equivalent to
x = 3^4
= 81
This is Choice D.
Thank you,
