c
Step-by-step explanation:
The shaded portion area A corresponds to the area Ao of the outer circle minus the area Ai of the inner circle:
A = Ao - Ai
Also, the area of each circle of radius r is given by:
π r²
where the radius r is half the diameter d.
So, using r = d/2 in the above formula, we obtain:
π r² = π (d/2)² = (π/4) d²
Now, replacing each area with the corresponding diameter, we find:
A = Ao - Ai
= (π/4) 4² - (π/4) 1.5²
= (π/4) (4² - 1.5²)
= (π/4) (16 - 2.25)
= (π/4) (13.75)
≅ 10.799
Rounding the result to one decimal place, we find the answer:
10.8 m²

Answer:
4 ounces per cup
Step-by-step explanation:
To find the unit rate, we take the ounces and divide by cups. We want a 1 in the denominator
3 ounces÷3/4 cup
Copy dot flip
3 ounces * 4/3 per cup
4 ounces per cup
The remainder when the polynomial f(x) = 3x³ - 4x² + 2x + 8 is divided by (x - 5) is constant an equal f(5).
Substitute x = 5 to the polynomial:

Answer: (3x³ - 4x² + 2x + 8) : (x - 5) = q(x) + 293.
