suppose MarryAnn puts 5 gallons of gas in her car and can drive 155 miles. Her gas tank holds 18 gallons of gas. How many miles
1 answer:
She can drive 558 miles with 18 gallons of fuel.
Step-by-step explanation:
Given,
Distance traveled with 5 gallons = 155 miles
Distance traveled with 1 gallon =
Total fuel hold by tank = 18 gallons
Total distance = Distance traveled with 1 gallon * Total fuel hold by tank
Total distance =
Total distance = 558 miles
She can drive 558 miles with 18 gallons of fuel.

The hardest part is finding the length of the curve at the top. To find arc length, multiply the circumference by the arc angle divided by full angle (360°) in a circle. Or:
x, the arc angle in a semicircle, is 180°.
r, the radius is 7/2 = 3.5.
Now just plug the numbers in and solve for arc length, s.
s = 2π(3.5)(1/2) ≈ 11.00
Now just add up all the sides. 11cm + 10cm + 10cm + 7cm = 38 cm.
