Solve for a! 264=π×a×(20-a) Thank you!

Mathematics
1 answer:
jasenka [17]3 years ago
4 0

Answer:

a ≈ 14 or 6

Step-by-step explanation:

264 = π × a × (20 - a)

a(20 - a) = \frac{264}{Pi} ≈ 84 (rounded off to nearest whole number)

Opening the brackets we get;

a² - 20a + 84 = 0

Applying the quadratic formula we get:

a ≈ 14 or 6

Alona [7]

Answer:

  5 miles

Step-by-step explanation:

distance = speed · time

Tom's distance = (50 mi/h)·(2.5 h) = 125 mi

Albert's distance = (65 mi/h)·(2 h) = 130 mi

Albert drove 130 -125 = 5 miles farther than Tom.
