Work out the area of this circle.

Mathematics
1 answer:
mylen [45]4 years ago
5 0

→Answer:

50.3cm^2

→Step-by-step explanation:

Well the formula for the area of a circle is \pi r^2.

<u><em>→Given information</em></u>

Pi is 3.142

radius is 4 cm

answer must be rounded to the nearest tenth

____________________________________________________________

So now we have to plug in the given information into the following formula \pi r^2.

(3.142)(4)^2

So now we have to solve this formula using PEMDAS.

So 4 squared is 16 and 16*3.142 is 50.272cm^2.

The question clearly states the given answer must be rounded into the nearest tenth so 50.272 is 50.3 cm^2.

The median for the given set of six ordered data values is 30.5.
nikdorinn [45]

Answer:

x = 15

The median is the middle number, however, in this case there are two:

25 and x

The formula is:

23 + x/2 = 30.5

Subtract 23 from both sides:

23 + x - 23 = 30.5 - 23

Simplify:

x/2 = 7.5

Multiply both sides by 2:

2x/2 = 7.5 ⋅ 2

Therefore:

x = 15

A large hose can fill 7/8 of a water tank in one hour. A small hose
luda_lava [24]

Answer: 1/8

Step-by-step explanation:

From the question, we are informed that a large hose can fill 7/8 of a water tank in one hour while a small hose

can fill 3/4 of a water tank in one hour.

To get the solution to the question above, we have to find the difference between the amount if water filled by the large and the smaller hose. This will be:

= 7/8 - 3/4

= 7/8 - 6/8

= 1/8

Solve the right triangle shown in the figure BC = 1.6in&lt; A=48.8 C =90
yKpoI14uk [10]
Drawing a diagram to represent the information you've given, the only angle we are missing is B.  We can find that by subtracting the two we're given from 180:
180 - 90 - 48.8 = 41.2
<em>m</em>∠<em>B</em> = 41.2°.
We can use the angles and the one side we're given to find the remaining sides.  Since we do not know the length of the hypotenuse, AB, we cannot use sine or cosine.  We must use tangent (the ratio for tangent is opposite/adjacent):
\tan 41.2 = \frac{x}{1.6}
Multiply both sides by 1.6:
1.6 \tan 41.2 = x&#10;\\ 3.67 = x
This is the length of side AC, which is opposite to angle B.
To find the length of AB we can use the Pythagorean Theorem:
(1.6)^2+(3.67)^2=c^2&#10;\\ 2.56+13.4689=c^2&#10;\\ 16.0289=c^2&#10;\\ \sqrt{16.0289} = \sqrt{c^2}&#10;\\ 4=c
The length of side AC, the hypotenuse, is 4 inches.
