Circles+1Y

It is True that you need to have two Pieces of Information to find the area of a Circle because you can either use the radius squared or the diameter(they both are the same) then multiply it by Pi(aprx. 3.14) then you have your answer. Thank you By:Aymen Ibrahim

Area, Circumference and Diameter of a Circle 3. Two pieces of information are needed to find the area of a circle. o True 
 * The area of a circle can be found by multiplying pi ¶ (which is equal to 3.14) by the square of the radius
 * If a circle has a radius of 4, its area is 3.14*4*4=50.24
 * If you know the diameter, the radius is 1/2 as large.

Finding the circumference of a circle

Two pieces of information are needed to find the area of a circle. o True

example: to find the area of a circle you need the formula. which are the two things radius, and pi radius squared x pi

Irrational Numbers 16. The measurement for the circumference of a circle will be an irrational number. o True example: an irrational number is a decimal that goes on an on with no definite pattern, this is what the circumference is.

Chelsea Starks 3. Two pieces of information are needed to find the area of a circle. o True o False A: True Two pieces are needed to find the area of a circle. One of those things are the radius of a circle so that it can be squared or the diameter and the second is the simple numerical equivalent of pi.

1. Breaking up a problem into parts is a strategy that can be used for solving complicated problems. x True o False

Yes because breaking up larger problems in to smaller problems is easier then doing them whole because say if it is a really long equation you can simplify it it can make the large complicated more simple.

2. The area of any triangle is always half of the area of a rectangle that can be drawn around it? x True o False Yes the area of any triangle is have the area of a rectangle that can be drawn around it if it is a right triangle it can be half of a rectangle a equalaterial triangle in the middle of a rectangle can also be half of a rectangle.

Radius and Pie

Donna Survillo 1. Breaking up a problem into parts is a strategy that can be used for solving complicated problems. True. For an example, I'll use KF-34. First I didn't understand the problem because I was paying attention to how long and confusing the problem was and not the individual parts such as C=2πr and C=πd. When I broke down the problem, I realized that they were the same because when you have C=2πr, it's telling you to multiply the radius by 2 which will give you the same length of the diameter (the same answer as C=πd). 2. The area of any triangle is always half of the rectangle's area that can be drawn around it. True. If you draw a rectangle around a triangle and split the triangle in half (down the center), you'll get four equally sized triangles and 2/4 of those triangles will be the cut in half triangle from the beginning.

Area, Circumference and Diameter of a Circle 3. Two pieces of information are needed to find the area of a circle. o True o False Of course it's true mainly because the formula for solving the area is R squared•¶. So if you have only the diameter divide it by 2 because the radius is what's that needed. So if the radius is 4 it would be 4•4 which equals to 16. Then times it by ¶ which round off to about 3.14 make it simple instead of being an irrational number being the area of 50.24 squared because it's the area.
