Determine the area of each semicircle or quarter circle. Think carefully about whether the length you are given corresponds to a radius or a diameter. Give your answers to the tenths decimal place (1 decimal such as 3.4) and DO NOT include the units because it is very difficult to do in the answer field because these are all squared. Use 3.14 for LaTeX: \piπ. Remember the formula for Area of a Circle is: LaTeX: A=\pi r^{^2}

Area of semicircle = 1/2(πr^2)

Area of quarter circle = 1/4(πr^2)

Step-by-step explanation:

The question is incomplete. You didn't provide the diagrams for the semicircle and quarter circle to evaluate the areas. I would explain how to find the area of a semicircle and quarter circle.

Area of a circle = πr^2

where r = radius and π = 3.14

If diameter (d) is given: d = 2r

To get radius, divide diameter by 2.

r = d/2

A semicircle is half of a circle.

Area of a semicircle is half the area of a circle.

Area of a semicircle = 1/2(πr^2)

A quarter circle is a quarter of a circle.

Area of a quarter circle is quarter of the area of a circle.

Area of a quarter circle = 1/4(πr^2)

parallel and congruent

step-by-step explanation:

the movement of translation is linear.   these have the same translation because you are using the same rule for each point of the triangle so you will see the same slope being used to get from a point on the triangle to its image.

same slope!   you should think parallel when you see those 2 word together (well unless it's the same line but it can't be because we are coming from different points here)

congruent! because each point is being moved the same distance.
