Answer:
Surface area of cylinder = 50.26 unit² (Approx.)
Step-by-step explanation:
Given:
Radius of base r = 2 units
Width of lateral rectangle = 4 units
Length of lateral rectangle = 6.28 units
Find:
Surface area of cylinder
Computation:
Surface area of cylinder = 2[Area of base] + Area of lateral rectangle
Surface area of cylinder = 2[πr²] + [l][b]
Surface area of cylinder = 2[(22/7)(2)²] + [6.28][4]
Surface area of cylinder = 2[(22/7)(4)] + 25.12
Surface area of cylinder = 25.14 + 25.12
Surface area of cylinder = 50.26
Surface area of cylinder = 50.26 unit² (Approx.)

You flip a coin 50 times. Of the 50 flips, the coin landed on heads 30 times. Use the questions below to compare the experimental probability of flipping heads with the theoretical probability of flipping heads.
Given:
Of the 50 flips, the coin landed on heads 30 times.
To find:
The experimental probability of flipping heads and compare it with the theoretical probability of flipping heads.
Solution:
We have,
Total number of trials = 50
Total number of heads = 30
The experimental probability of flipping heads is:
[tex]\text{Experimental probability}=\dfrac{\text{Total number of heads}}{\text{Total number of trials}}[/tex]
[tex]\text{Experimental probability}=\dfrac{30}{50}[/tex]
[tex]\text{Experimental probability}=\dfrac{3}{5}[/tex]
[tex]\text{Experimental probability}=0.6[/tex]
A coin has two sides one is heads and another is tails. So, the theoretical probability of flipping heads is:
[tex]\text{Theoretical probability}=\dfrac{1}{2}[/tex]
[tex]\text{Theoretical probability}=0.5[/tex]
Therefore, the experimental probability of flipping heads is 0.6 and the theoretical probability of flipping heads is 0.5. So, the experimental probability is greater than the theoretical probability of flipping heads.
A cylinder has a volume of 791.28 cubic centimeters. The height of the cylinder is 7.0 inches. Calculate the radius of the cylinder. Use 3.14 for π.
Answer:
The radius is 6
[tex] \sqrt{v \div \pi \times h =} [/tex]
=791.28/3.14×7.0
=
[tex] \sqrt{36} [/tex]
=6
The radius of cylinder is 3.764 cm.
What is volume?Each thing in three dimensions takes up some space. The volume of this area is what is being measured. The space occupied within an object's borders in three dimensions is referred to as its volume. It is sometimes referred to as the object's capacity.
Finding an object's volume can help us determine how much material is needed to fill it, such as how much water is needed to fill a bottle, aquarium, or water tank.
Given volume of cylinder = 791.28 cm³
height = 7.0 inches
so, 1 inch = 2.54 cm
7 inch = 2.54 x 7 = 17.78 cm
height = h = 17.78 cm
volume of cylinder = πr²h
where r = radius
V = πr²h
791.28 = 3.14(17.78)r²
r² = 791.28/55.8292
r² = 14.1732
r = √14.17732
r = 3.764 cm
Hence the radius is 3.764 cm.

Is it

B.)A=28,B=34
C.)A=35,B=28
D.)A=34,B=28
Answer:
D. A=34, B=28
Step-by-step explanation:
In the bulletin points, it says that seconds 3-5 are decreasing. That means that those heights can't be higher than second 2 (34). The only option that works is option D.
----------------------
Option A is incorrect because it starts with 35ft which is higher than second 2(34) so that is automatically wrong.
Option B is incorrect because it is increasing instead of decreasing.
Option C is incorrect for the same reason as Option A: it starts with 35ft.
---------------------
Therefore, the only correct option is Option D.

Elsa drove 864 miles in 12 hours.
At the same rate, how many miles would she drive in 8 hours?
Answer:
576 miles
Step-by-step explanation:
Answer:
else will drive 567 miles in 8h
Step-by-step explanation:
take 864÷ 12 to get how many hours she drives in one hour
you get 72
then you take 864÷2 to get how many miles she'll drive in 6h
you get 432
then you take 432 and add 144 or 72 + 72
and you get 567 miles in 8h

137
Step-by-step explanation:
43+ z=180
z=180-43
= 137
Answer:
137°
Step-by-step explanation:
Subtract 43 from 180
180 is the degree of a straight line
Angles y and 43 degree angle are equal so to find z you subtract the 43 from 180
180 - 43 = 137
