Answer:

n = 12

Step-by-step explanation:

Rewrite it as $\frac{(n+3)}{5} = 3$

Multiply both sides by 5

(n+3) = 15

You can drop the parenthesis now.

n + 3 = 15

n = 12

The formula of an area of a circle:

$A=\pi r^2$

r - a radius

We have r = 14m. Substitute:

$A=\pi\cdot14^2=196\pi\ m^2$

If you want an approximate area, you can accept $\pi\approx3.14$

Then:

$A\approx196\cdot3.14=615.44\ m^2$

Temperature after 3 seconds is 25.9°C

3) f(t) = 35 means after t seconds, temperature was 35°C

4) 35 = 22 + 1.3t
