Area of a circle is found using the formula: Area = π * r^2
Using 3.14 for π
Area of the bull'e eye = π * 2^2 = 4π = 4 * 3.14 = 12.56 square inches.
This is 20% of the entire target.
To find the area of the entire target, divide the area of the bull's eye by the percentage:
Area = 12.56 / 0.20 = 62.8 square inches.
Round the answer as needed.
Answer:
Area of target = 62.8 inch²
Step-by-step explanation:
A bull’s-eye with a 4-inch diameter covers 20 percent of a circular target.
Diameter of bull's eye = 4 inch
Given that bull’s-eye covers 20% of circular target.
Area of target = 62.8 inch²
Answer:
7/500 or Answer Choice B
Step-by-step explanation:
1. First find the total # of ALL the marbles in the bag. (75 + 50 + 100 + 25 = 250)
2. Then define the percentage of each marble color in said bag.
3. Double check that the percentage = 100. (yes)
4. Understand that she could pick the said marble colors not in the order that was specified, so to determine the chances of picking the right colors in the right order. Multiple the values.
red marble: 1/10 chance
green marble: 2/10 or 1/5 chance
blue OR orange (this means add together and then divide by total: 250): 7/10 chance
multiply fractions: 1/10 x 1/5 x 7/10 = 7/500 (this is simplified)
5. Select Answer Choice (B)
