Find the value of the circumference of a circle with the given diameter.

1 answer:

7 0

C= 2πr, and 2r = D (diameter). So, you can also use this equation: C =Dπ
Since we know the diameter, and we know the value of π, we can easily calculate the value of circumference.
C = Dπ
C = 3.21π
This means that the correct answer is B. 3.21 pi

Given expression ;

9(5x + 1) ÷ 3y

Follow the BODMAS rule;

Step 1; Divide

$\rm \frac{9(5x+1)}{3y} \\\\ \frac{3(5x+1)}{y} \\\\$

Step 2; Multiply

$\rm \frac{9(5x+1)}{3y} \\\\ \frac{(15x+3)}{y} \\\\$

Hence the expression obtained after solving the given expression is, $\rm \frac{(15x+3)}{y}$
