Subtract $15.98, $7.99, $0.50, and 3.59 from $40.00
Step-by-step explanation:

Answer:
A ≈ 1900.7 m²
Step-by-step explanation:
The area (A) of the race track is
area of outer circle - area of inner circle
= πR² - πr²
= π × 63² - π × 58²
= π (63² - 58² )
= π(3969 - 3364)
= π × 605
≈ 1900.7 m² ( to 1 dec. place )
Answer:

Step-by-step explanation:
<u>Given:</u>
Base = b = 2 in.
Perpendicular = a = 2 in.
<u>Required:</u>
Hypotenuse = c = ?
<u>Formula:</u>
(Pythagoras Theorem)
<u>Solution:</u>
c² = (2)² + (2)²
c² = 4 + 4
c² = 8
Taking sqrt on both sides
c = 2.8 in.
