It is irrational.
A = π r^2 = π[3/4 cm]^2 = 9π/16 cm^2
An irrational number (Pi in this case) multiplied by a rational number (9/4) gives an irrational number.
Answer:
$11.9
Step-by-step explanation:
We are given;
The cost of the cell phone is $170
Tax rate is 7%
We are required to find how much tax is paid on the cell phone.
The tax rate is 7% of the cost of the cell phone
That is;
7% of $170
also; 7/100 of $170
Thus, tax paid = 7/100 × $170
= $11.9
Thus, the tax paid on the cell phone is $11.9
First subtract 3 from 51 which gives you 48, then divide 48 by 3 which gives you the answer of 16.
If r=-3, then it would be -3-12 which equals -15
