Answer:
10 units
Step-by-step explanation:
1. Do the square in the middle
2 x 2 = 4
2. Do the triangle on the left
2 x 2 divided by 2 = 2
3. Do the triangle on the right
4 x 2 divided by 2 = 4
4. Add them all up
4 + 2 + 4 = 10
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.
10 x 25 = 250, well 20 x 25 is just double that, its 10 doubled x 25 so he probably just added it up. repeated addition really helps with times tables.
Question A
take $100.80 divide it by 35 which would equal 2.88
so round that up for 3.0 for the closest answer
Question B
take 49.2 and divide it by 6 which would equal 8.2
so round it to the nearest number which would be 8.0
Question C
take 0.78 and divide it by 20L which would equal 0.039
so round that up to the closest number which would be 0.04L
