Answer:
A ≈ 4298.66 in²
Step-by-step explanation:
The area (A) of a circle is calculated as
A = πr² ( r is the radius )
Here diameter = 74, then r = 74 ÷ 2 = 37 , then
A = π × 37² ≈ 3.14 × 1369 ≈ 4298.66 in² ( to the nearest hundredth )

(5x-7)(3x-8)
Expand using FOIL (multiply the firsts, then outers, then inners, then lasts):
Firsts: 5x * 3x = 15x²
Outers: 5x * -8 = -40x
Inners: -7 * 3x = -21x
Lasts: -7 * -8 = 56
Combine them all together:
15x² - 40x - 21x + 56
15x^2 - 61x + 56
