matrenka [14]

Answer: 18 quarters & 15 pennies

Step-by-step explanation:Q + p = 33

0.25q + 0.01p = 4.65

p = 33 - q

0.25 q + 0.01 (33 - q) = 4.65

q = (4.65 - 0.33)/(0.24)

q = 18

p = 33 - 18 = 15

Answer:

616 square centimeters

Step-by-step explanation:

Area of a circle is equal to pi × r^2. In this case, they have asked that you substitute 3.14 or 22/7 for pi, so I will be using 22/7, instead.

Diameter is equal to 2r; to find the radius, simply divide 28 by two. This gives us a radius of 14.

Multiply 14 squared by 22/7:

(22/7)(14^2)

This gives us (22/7)(196); (4312/7); 616.

Therefore, the area of the circle is approximately 616 square centimeters.
