A bookmark is shaped like a rectangle with a semicircle attached at both ends. The rectangle is 16 cm long and 4 cm wide. The di
ameter of each circle is the width of the rectangle. What is the area of the bookmark? Use 3.14 for π.
1 answer:
Answer: 76.56sqcm
Step-by-step explanation:
Area of rectangle= length * width
= 16 * 4 = 64sqcm
Area of semicircle= (1/2)(r^2)π
r= d/2= 4/2= 2
Area of semicircle= (1/2)(2^2)(3.14)
= 6.28sqcm
Area of bookmark= Area of rectangle + 2*Area of semicircle
Area of bookmark= 64 + 2(6.28)
=64 + 12.56 = 76.56sqcm

Answer:
Step-by-step explanation:
y = 3x -6
x = -2, y = -12
x = -1, y = -9
x = 0, y = -6
x = 1, y = -3
x = 2, y = 0
x= 3, y = 3
x -2 -1 0 1 2 3
y -12 -9 -6 -3 0 3
I'm 100% sure the answer is d. II and IV
because $257.72 - $248.53 = $9.19
and $73.98 - $64.79 - 9.19
