The radius of a circle is just half the diameter. So to find the radius from the diameter, just divide the diameter by 2:

$radius=\frac{diameter}{2} = \frac{5 \text{ mm}}{2} =2.5 \text{ mm}$

That's the radius.

2^6 because

2 times 2 times 2 times 2 times 2 times 2 is 64

2 times 2 is 4 times 2 is 8 times 2 is 16 times 2 is 32 times 2 is 64

PLEASE HELP!! WILL GIVE BRAINLIEST!!!

Answer:

option D

Step-by-step explanation:

Jerry solved this equation:

$3(x-\frac{1}{4})=\frac{13}{6}$

In the first step , she multiplied 3 inside the parenthesis

1. $3x-\frac{3}{4}=\frac{13}{6}$

In step 2, 3/4 is added on both sides

2. $3x-\frac{3}{4}+\frac{3}{4}=\frac{13}{6}+\frac{3}{4}$

In step 3, we take LCD 12

3. $3x=\frac{26}{12}+\frac{9}{12}$

In step 4, add the fractions

4. $3x=\frac{35}{12}$

Here, 3 or 3/1 are same.

$\frac{3}{1}x=\frac{35}{12}$

In step 5, to remove 3/1 we multiply both sides by 1/3.

Instead of multiplying 1/3 , Jerry made an error by multiplying 3/1

$\frac{1}{3} \cdot \frac{3}{1}x=\frac{1}{3} \cdot \frac{35}{12}$

$x=\frac{35}{36}$

In step 5, he should have multiplied both sides by 1/3
