The surface area of the figure with a diameter of 6cm and height of 25cm is 84π square cm
The total surface area of a cylinderThe formula for calculating the TSA of a cylinder is expressed as:
S = 2πr(r+h)
Since the figure is half of a cylinder, hence;
S = πr(r+h)
Given the following
r = 6/2 = 3cm
h = 25cm
Substitute
S = π(3)(3+25)
S = 84π square cm
Hence the surface area of the figure below is 84π square cm

Arianna went running for 0.75 hours and ran 5.55 miles. What was her speed, in miles per hour, if Arianna
ran at the same speed for her whole run?
Answers
Answer:
7.4 miles per hour
Step-by-step explanation:
To find her speed in miles per hour, divide the amount of miles she ran by the number of hours:
5.55/0.75

Step-by-step explanation:
Answer:
39 degrees
Step-by-step explanation:
by the triangle angle sum theorem, the 3 angles of triangles must add up to 180 degrees.
Therefore, 102 degrees + 39 degrees + x = 180 degrees
141 degrees + x = 180 degrees
x = 39 degrees
The combined ages of megan and kyle are 27. if kyle is twice as old as megan, how old is kyle.
Answers
kyle is 18 and megan is 9, because 9 + 18 = 27 and 27 / 3 = 9. hope this helps :)
Answer:
Kyle's age = 18 years
Step-by-step explanation:
Let Megan's age = x
Kyle's age = 2x
Combined ages of Megan and Kyle = 27
x + 2x = 27
3x = 27 {Divide both sides by 3}
3x/3 = 27/3
x = 9
Megan's age = 9 years
Kyle's age = 2 * 9 = 18 years
water flows through a pipe at a rate of 7 cubic meters per month. Express this rate of flow in gallons per minute. Round your answer to the nearest hundredth.
Answers
Answer:
0.04
Step-by-step explanation:
The rate of flow is 0.043 gallons per minute.
How to convert litres to gallons ?Divide by 0.264 to obtain litres from gallons and multiply by 0.264 to obtain in gallons from litres.
According to the given question
Water flows through a pipe at a rate of 7 cubic meters per month.
We know 1 cubic meter is = 1000 litre
∴ 7 cubic meters per is
= (7 × 1000) litre
= 7000 litre
= (7000 × 0.264) gallons
= 1848 gallons per month
Now 1 month is
= ( 1 × 30 × 24 × 60 ) minutes.
=43200 minutes
So in 43200 minutes 1848 gallons of water flows through that pipe
∴ In a unit minute or per minute it the rate of flow will be
= 1848/43200 gallons per minute
= 0.043 gallons per minute.

A ship must have 1 lifeboat for every 12 passengers, plus one lifeboat for
the crew and one backup lifeboat. Which equation shows the
relationship between the number of passengers, p, and the number of
lifeboats needed, I?
Select one
1) I= 2 + 1/2
2) I= 2p + 10
3) I= 12p
4)I=2+ p/12
Answers
===========================================
Explanation:
p = number of passengers
L = number of lifeboats
Since we're grouping the passengers in groups of 12, this strongly implies we'll be dividing two values. Specifically we have p divided by 12 to represent the number of boats we will need just for the passengers.
For example, let's say p = 36. This means we have 36 passengers. That would mean we need p/12 = 36/12 = 3 boats for those 36 passengers. This excludes the crew and backup boat. Adding those two extra boats leads to the expression 2 + p/12 which is the total number of lifeboats needed.
In the event that p is not a multiple of 12, this leads to p/12 not being a whole number. We could have say p = 50 passengers which means p/12 = 50/12 = 4.167 approximately. We will not round this to 4 because then we'll have passengers without a lifeboat.
We must round 4.167 up to the nearest whole number to get 5. The first four boats take care of 4*12 = 48 passengers, while that 5th boat handles the remaining 50-48 = 2 people. Since 2 people in a boat seems like a really low count, the crew could likely spread the people out such that say 10 people would be in each boat (since 50/10 = 5).
So in short, the result of p/12 is rounded up to the nearest whole number.

100 times 5 is 500
so 100 is cancelled and 500 becomes 5
therefore 18.5 times 5 is equal to 92.5
Answer:
92 1/2 or 92.5
Step-by-step explanation:
how to solve?
Put it into a percent proportion :D!
Percent proportion is is/of=%/100 or a/w=p/100
The a stands for "part"
and the w stands for "whole"
p stands for "percent"
Is/of=%/100 will help you figure it out if it's in a mathmatical sentence.
Since they did NOT give you what the "is" is, you put the variable "a"
a/ =
Next,
Since it said "of"
You put of underneath the unknown number "is" (a)
a/500=
Now put in the percent
a/500=18.5/100
Now cross multiply!
Then you should get 92.5!

The weight of a baby dog on day one is 5 kilograms. Every day, the dog grows an additional 0.1 kilograms. How heavy the dog is after 10 days?
Answers
Unit rate is the quantity of an amount of something at a rate of one of another quantity.
The weight of the dog after 10 days is 5.9 kg.
What is a unit rate?It is the quantity of an amount of something at a rate of one of another quantity.
In 2 hours, a man can walk for 6 miles
In 1 hour, a man will walk for 3 miles.
We have,
Weight of the baby on day one = 5 kg
This can be written as,
1 day = 5 kg
The dog grows 0.1 kg each day.
This means,
On the 2nd day, we get,
2 days = 5 + 0.1
2 days = 5.1 kg
The expression for the weight of the dog on n days can be written as,
n days = 5 + (n -1) x 0.1 _____(1)
Now,
After 10 days we get,
n = 10
From (1) we get,
10 days = 5 + (10 - 1) x 0.1
10 days = 5 + 9 x 0.1
10 days = 5 + 0.9
10 days = 5.9 kg
Thus,
The weight of the dog after 10 days is 5.9 kg.

The figure is basically 8+8+circumference of a circle with 8 diameter. The circumference is 2pi(4) which is 50.27, and you add 16 to that. This gives you the answer 41.13
Thanks to garden555 for pointing out my mistake.
Answer:
60m / 41.12 m
Step-by-step explanation:
side of square is 8m
hence, radius of the semicircle is 1/2 of 8
= 4m.
2semicircles = 1 circle.
perimeter of a circle = 2πr
Taking value of π as 22/7,
= 2 x 22/7 x 4
= 176/4
= 44m
OR
Taking value of π as 3.14,
= 2 x 3.14 x 4
= 25.12m
hence, perimeter of figure is,
44 + 8 + 8 = 60m
OR
25.12 + 8 + 8 = 41.12 m
