The missing numbers are 66 and76.
Answer: B.pi/2
ABCD is a square
=> Δ ABD is a isosceles right triangle at A
using pythago theorem, we have:
AB² + AD² = BD²
=> 2AD² = 4
⇔ AD² = 2
⇒ AD = √2
through O, draw EF parallel to AD and BC
=> EF is diameter
because EF//AD => EF = AD = √2 (because circle O is inscribed the square ABCD)
=> the area of the circle is

Answer:
x=24/7
Step-by-step explanation:
3(x+2)+4(x-5)=10
3x+6+4(x-5)=10
3x+6+4x-20=10
7x+6-20=10
7x-14=20
7x=24
x=24/7
Answer:
338 tiles
Step-by-step explanation:
First, convert the measurements of the kitchen from feet to inches by multiplying each measurement by 12.
102 * 12 = 1224 18 * 12 = 216
Now multiply these answers together.
1224 * 216 = 264,384 square inches
Now find the area of the vinyl tiles.
28 * 28 = 784 square inches
Now find how many 784 square inch tiles are needed to cover a 264,384 square inch kitchen.
264,384 / 784 = 337.224
Since you can't buy part of a tile, round your answer up.
338 tiles
