Determine the area of each semicircle or quarter circle. Think carefully about whether the length you are given corresponds to a
VashaNatasha [74]

Answer:

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)

Further explanation with diagram has been added as as an attachment.

Equation for this slope
spin [16.1K]

Answer:

m = y1 - y2/ x1 -x2

Step-by-step explanation:

Your coordinates are (4, 1) and (0, -3) so m (slope) equals 1 - (-3) over 4 - 0 = 4/4 = 1
