Zarrin [17]

Answer:

18 hours

Step-by-step explanation:

we know that

Amy's dad drove the car at a constant speed and travel 585 miles in 13 hours

so

using proportion

Find out how long would it have taken the family to travel 810 miles

Let

x -----> the time in hours to travel 810 miles

$\frac{585}{13}\frac{miles}{hours}=\frac{810}{x}\frac{miles}{hours}\\\\x=13(810)/585\\\\x=18\ hours$

kodGreya [7K]

Answer:

18.84

Step-by-step explanation:

Circumference = 2πd

where d = diameter

the shape given has a diameter of 6

to find the circumference we simply plug in the value of the diameter as well as π into the formula

formula : C = πd

π = 3.14 and d = 6

C = 3.14(6) = 18.84cm
