Answer: 56.7 ft^2

Step-by-step explanation: The area of a circle is (pi)r^2

According to the problem, the height of the circular mural is 8.5 at its center. I’m assuming this means that this measurement is the diameter, which means we need to divide by 2 to get the radius.

8.5/2 = 4.25

Using pi as 3.14: (3.14)4.25^2 = 56.72

If a secretary typed 10,800 words in 2 hours and 30 minutes, how many words per minute did she type? ( Hint: Change hours to min
melamori03 [73]
<h3>Answer:  72 words per minute</h3>

Work Shown:

1 hour = 60 min

2 hours = 120 min (multiplied both sides by 2)

2 hours + 30 min = 120 min + 30 min = 150 min

speed = (number of words typed)/(time taken)

speed = (10800 words)/(150 min)

speed = (10800/150) words per minute

speed = 72 words per minute

AB is Tangent to circle O at B. if AB = 7 and AO = 17.4, what is the length of radius r to the nearest tenth?
irakobra [83]
The angle the radius makes with AB is a right angle, so the Pythagorean theorem applies.
  r² = 17.4² - 7² = 253.76
  r = √253.76 ≈ 15.9

The length of radius r is about 15.9.
