Marcus and three of his friends are guessing the radius of a circular pond. they read that the circumference is 157 ft, so they can use the equation 3.14*2r=157 to determine which of these guesses which form the replacement set {20,25,30,35} is correct? . what is the radius of the pond? a. 20ft b. 25ft c. 30ft d. 35ft

Option B. 25 ft

Step-by-step explanation:

we know that

The circumference of a circle is equal to

we have

assume

substitute in the formula

Solve for r

Divide by 2(3.14) both sides

Step-by-step explanation:

Given:

A triangle is drawn on the coordinate plane. It is translated 4 units right and 3 units down.

It is translated 4 units right and 3 units down.

We need to find the rule of translation.

Solution:

Now to the right of the axis which is positive of X axis and 4 units to the right means 4 units are added to X co-ordinate.

Also to the Down of the axis which is negative of Y axis and 3 units to the down means 3 units are Subtracted to Y co-ordinate.

Hence The co-ordinates at which triangle is drawn is
