Cory has designed a special table with a circular cutout
in the center to be filled with glass. The radius of the
cutout is 7 inches. What is the area of the tabletop after
he cuts out the inner circle? Use 3.14 for it and round
the answer to the nearest whole number.
154 square inches
12,463 square inches
9,847 square inches
12,309 square inches

12309 square inches

Step-by-step explanation:

Area of a circle = pi * r^2

Required area = Area of table - Area of cutout

= pi * 63^2 - pi * 7^2

= 3.14 * ( 63^2 - 7^2 )

= 12308.8 ≈ 12309

answer: c.  

step-by-step explanation:

mixtures containing substances that get attracted to magnet can be separated using a magnet. we can separate iron from a mixture of sand and iron, as only iron attracts to the magnet.

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides
