Answer:
8 π .
Step-by-step explanation:
radius increases at a constant rate of 1 in/sec.
dr / dt = 1
where r is radius .
radius after 4 sec
r = 1 x 4 = 4 in
area A = π r²
differentiating both sides
dA / dt = 2 π r dr / dt
Putting dr / dt = 1 , r = 4 in
dA / dt = 2 π x 4 x 1
= 8 π sq in per sec.
Area increases at the rate of 8 π per sec.

Solution:
Let's name the three consecutive numbers as y, y + 2, and y + 4.
<u>Note that:</u>
- => Equation formed: 3(y) = 2(y + 4)
<u>Solve the equation to find the three consecutive numbers.</u>
- 3(y) = 2(y + 4)
- => 3y = 2y + 8
- => 3y - 2y = 8
- => y = 8
The numbers are 8, 10, and 12.
