Answer:

Step-by-step explanation:

a=3400t+600, we put in 21,000 for a. Because we have to find 't' when 'a' is 21,000.

which will give us 21,000 = 3400t+600.

Then,Subtract 600 to both sides to get 20,400 = 3400t

Divide both sides by 3,400 and you get 6 = t.

The ans is 6 minutes. The plane will take 6 min to reach the altitude 21,000 feet

Area of a Circle: A = πr²
d = 2r

Step-by-step explanation:

Step 1: Define

d = 4 m

Step 2: Find r

Substitute: 4 = 2r
Isolate r: 2 = r
Rewrite: r = 2 m

Step 3: Find Area

Substitute: A = π(2)²
Substitute: A = (3.14)(2)²
Evaluate: A = (3.14)(4)
Multiply: A = 12.56 m²
