Answer:
120 miles
Step-by-step explanation:
Albert travels 40 miles for each hour he drives (units = mph = miles per hour)
If he drives 3 hours at 40 miles per hour...
3 hours x 40 miles / hour = 120 miles
You need 864.52 sq. in. of blue tile.
We need to find the area of the large circle (including blue and yellow) and the area of the yellow circle.
We have the circumference of the blue circle, 113.097.
C = πd
113.097 = 3.14d
Divide both sides by 3.14:
113.097/3.14 = 3.14d/3.14
36.018 = d
The diameter is twice as much as the radius, so r = 36.018/2 = 18.009.
The area of a circle is given by the formula
A = πr²
A = 3.14(18.009)² = 1018.38 sq. in.
The area of the small yellow circle is given by
A = 3.14(7²) = 3.14(49) = 153.86
Subtracting these two, we have
1018.38 - 153.86 = 864.52 sq. in.
Answer:7.25 feet
Step-by-step explanation:
6.25+6.5=12.75
20-12.75=7.25
