Answer:
64pi
Step-by-step explanation:
To find the raidus we divide the diameter by 2
Radius = 16/2 = 8
Area = pi*8^2 = 64pi
To determine the number of modules that is in each story, we simply divide the number of modules by the number of stories.
= 140 / 14
Simplifying,
= 10 modules / story
Therefore, by even distribution we note that there are 10 modules per story.

Answer: 400 (choice A)</h3>
==============================================
Explanation:
40% + 35% = 75% of the coins were either made before 1940, or made from 1940 to 1980. In other words, 75% of the coins were minted before 1980. This leaves 100% - 75% = 25% of the coins to being minted after 1980.
25% of 1600 = 0.25*1600 = 400 coins were made after 1980

Answer:
2.83 for log2(x)
15.81 for log(2x)
Step-by-step explanation:
We can get the log function by itself by subtracting the constant and dividing by the coefficient.
5 +6·log2x = 14
6·log2x = 9 . . . . . . . subtract 5
log2x = 1.5 . . . . . . . divide by 6
At this point, we're not sure what is meant by log2x.
log₂(x) = 1.5 ⇒ x = 2^1.5 ≈ 2.83
log(2x) = 1.5 ⇒ x = (10^1.5)/2 ≈ 15.81
Answer:
<u>405</u>
Step-by-step explanation:
<u>Given</u>
<u>Solving</u>
- a₂ = -3a₁ = -3(5) = -15
- a₃ = -3a₂ = -3(-15) = 45
- a₄ = -3a₃ = -3(45) = -135
- a₅ = -3a₄ = -3(-135) = <u>405</u>
