Answer:
Before you write the answer to your question, make sure the question is asking for the actual value of pi or 3.14.
If the question was asking for the question to be completed with the ACTUAL VALUE of pi, then your answer is ----> 4.37
If the question was asking for the question to be completed with the rounded of pi (3.14), then your answer is ----> 4.38
It's a subtle difference, but remember, there is no such thing as close in math, it's either right or wrong.
Step-by-step explanation:
Given: Circle's Area, 60.12
<u><em>As the value of pi was not directly stated, I will divide the answer into 2 portions, portion one with the answer with the actual infinite value of pi, and one where I will describe how to do it with 3.14 as pi. </em></u>
Explanation with 3.14:
First thing first, know the formula for calculating the area of a circle:
stands for Area, and
stands for Radius
Now, plug in the given values:
Next, replace 3.14 for pi:
Then, divide both sides by 3.14 ,which gives us:
Please note: 19.15 is rounded
Anyway, to isolate , we take the square root of both sides:
The square root and square on the right side of the equation cancel out, and we are left with:
Please note that 4.38 was rounded
Answer:
Therefore the value is
Step-by-step explanation:
Given:
....Given
Step 1. Applying Distributive Property A(B+C)=AB+AC we get
Step 2. Add 15 both the side
Step 3. Dividing both the side by 9
Therefore the value is
Answer:
correct option is 2187
Total surface area is 2,185.44 square inches.
lateral surface area is 640.56 square inches
Step-by-step explanation:
Given
radius of cylinder = 12 inches
height of cylinder = 17 inches
we will us value of pi as 3.14
surface area for cylinder consist of two part
1. lateral surface area which is gven by
where r is radius of cylinder and l is height of cylinder
Thus, lateral surface area for given cylinder is
Thus, lateral surface area for given cylinder is 1281.12 square inches.
_________________________________
second part of surface area is area of two base (upper and lower) of cylinder.
area of base is given by area of circle
This, area of base is for one base of cylinder
since there are 2 base
area of both base will be = 2* area of one base
= 2*452.16 = 904.32.
Thus, area of base is 904.32 sq. in.
_______________________________________
Total surface area of cylinder = area of two base+ lateral surface area of cylinder = 1281.12 square inches + 904.32 square inches
= 2,185.44 square inches.
Thus, total surface area is 2,185.44 square inches.
lateral surface area is 640.56 square inches
but option which is closest to calculated value is 2187.
Thus, correct option is 2187

Note: this problem can be directly solved using formula
total surface area for cylinder =
