Step-by-step explanation:
X=275+55= 330 biked
y=275-55= 220 bus
First, find the area of the circle A=pi r^2 = 3.14 (8)^2=200.96
the radius is half the diameter so r=16/2=8
Second, find the area of the triangle A=(hb)/2=(8*16)/2=64
since the triangle is resting on the diameter of the circle that means the height of the triangle is also the radius of the circle so h=8 and b=16
Third, subtract the area of the triangle from the area of the circle to find the area of the shaded regions.
so...
200.96-64=136.96
is the answer.
W - the width
l - the length
P = 6984
P = 2w + 2l
l = 3w
substitute
2w + 2 · 3w = 6984
2w + 6w = 6984
8w = 6984 |:8
w = 873
l = 3 · 873 = 2619
Answer: the length = 2619 and the width = 873
Triangles are 180 degrees total so 80+40=120, subtract that from 180 and you’ll get B=60
