Answer:
B. 12 + 2pi cm
Step-by-step explanation:
The shaded region is made up of 3 square sides and one half circle. The three square sides are each 4, which means that those altogether equal 12.
The circle's circumference can be found by using the equation c = (d)pi
The diameter is 4, so the whole circumference is 4pi. However, you only need half of a circle, which is represented by 2pi.
Add them all together, and you get 12 + 2pi cm.
Answer:
63-degrees
Step-by-step explanation:
triangle = 180 degrees
46 + 71 + w = 180
117 + w = 180 *subtract 117 from both sides*
w = 63
Y=9/4x-5 is the standard form.
