Answer:
x = 125
Step-by-step explanation:
Given
= 25
Multiply both sides by 5 to clear the fraction
x = 5 × 25 = 125
x = 125
To solve this we are going to use the formula for the area of a circle:
where
is tte radius of the circle
We can infer that the bases of our cylinder are circles with 2 in radius, so
. Since we have tow circles, we are going to multiply the area by 2:
We can conclude that the <span>the combined area of the two bases of the cylinder is </span><span>
25.12 in.2</span>
8/12 is greater than 5/12.
This is easy to determine because both fractions have a common denominator, which is 12.
So we base our comparison solely in the numerator.
8 is greater than 5. Thus, 8/12 is greater than 5/12.
To further ensure that our answer is correct we can divide the fractions.
8/12 = 0.67 ; 5/12 = 0.42 ===> 0.67 is greater than 0.42
The math?you need to insert a picture
We can see that
There are four triangle on the surface
and five squares
For finding surface areas , we will find area of each surface and then add them
Calculation of area of triangle:
We are given
base=b=8
height=h=10
now, we can use area formula
Calculation of area of square:
base=width=8
There are four triangle and five squares on the surface
so, we can find surface area
SA=4* triangle + 5*square
so, surface area is .............Answer
