Ciara is making a new dance outfit. She needs 2 1/2 yards of fabric for the shawl. She needs 1 3/4 yards of fabric for the dress. If she has 3 yards of fabric, how much more does she need. If each yards of fabric cost 7.98, How much money does she need.

See explanation

Step-by-step explanation:

Amount of yards of fabric for the shawl = 2 1/2

Amount of yards of fabric for the dress = 1 3/4

Total amount of yards needed

= 2 1/2 + 1 3/4

= 2 2/4 + 1 3/4

= 3 5/4

= 3 + 1 1/4

= 4 1/4

Since she has 3 yards of fabric, the number of yards needed more will be:

= 4 1/4 - 3

= 1 1/4

If each yard = 7.98, the amount needed will be:

= 1 1/4 × 7.98

= 1.25 × 7.98

= 9.975

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
