Answer:
52 units
Step-by-step explanation:
1) 10m + n2/4
Substitute within the equation
2) 10(5) + (4)2/4

3) 50 + (4 x 2/4) = 50 + (4 x 1/2) = 50 + 2 = 52 units
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 )
