If the total area of a dartboard 30 000 mm² and the area of the target is 700 mm²
The probability of obtaining a target can be written as:
P = 700 mm² / 30 000 mm²
P = 0.0233
P = 2.3%
Therefore the correct answer is option B.
This, assuming the shooter has no experience and rolls the dart randomly within the dartboard area.

The circumference of the inner circle is 88 ft. The distance between the inner circle and the outer circle is 3 ft. By how many

Bogdan [553]

Answer:

18.86 feet

Step-by-step explanation:

The circumference of the inner circle is 88 ft.

Circumference of a Circle $=2\pi r$

Therefore:

$2\pi r =88\\r=88 \div (2*\frac{22}{7})=14 ft$

Radius of the inner circle=14 feet

If the distance between the inner circle and the outer circle is 3 ft, the radius of the outer circle=14+3 =17 feet.

Therefore. circumference of the outer Circle $=2\pi r$

$=2*\frac{22}{7}*17=106.86 ft$

Difference in Circumference=106.86-88 =18.86 feet

The circumference of the outer circle is greater than that of the inner circle by 18.86 feet.
