using 3.14 for Pi , since you didn't say what value to use
area = PI x r^2
Area of larger circle = 3.14 x 500^2 = 785,000 square units
area of smaller circles = 3.14 x 1^2 = 3.14 square units
785,000/ 3.14 = 250,000 small circles can fit into larger one
Answer:
432 in²
Step-by-step explanation:
To Obtian the square inches of wooden boards required :
Area of box = 2(l * w) + 2(l * h) + 2(h * w)
Length = 12 ; width = 6 ; height = 8
Hence,
Area of box = 2(12 * 6) + 2(12 * 8) + 2(8 * 6)
Area of box = 2(72) + 2(96) + 2(48)
Area of box = 432 in²
Answer:
x=0.76
Step-by-step explanation:
7x^2-10=18
7x^2=28
7x=square root 28
