Answer:
Area of rectangle = 448
Area of semi circle = 402.1
Total area = 850.1
Step-by-step explanation:
Area of rectangle = length times width
Given length = 32 cm
Given width = 14 cm
Area = 32 * 14 = 448
Area of semi circle = πr² / 2
where r = radius
Given diameter = 32cm
To convert diameter to radius simply divide by 2
32 / 2 = 16
So radius 16
now we plug 16 into the formula
[tex]A=\frac{\pi 16^2}{2} \\16^2=256\\256\pi =804.25\\\frac{804.25}{2} =402.12\\A=402.1[/tex](rounded)
Total area = area of semi circle plus area of rectangle
total area = 402.1 + 448 = 850.1
Answer:
Solution given:
length [l]:diameter [d]:32cm
breadth [b]:14cm
radius [r]=32/2=16cm
Area of semi circle:½πr²=½*πx16²=402.12cm²
+Area of rectangle:l*b=32*14=448cm²
=Total area =402.12cm²+448cm²= 850.12cm²

What common fraction is halfway between 1/8 and 1/10 on a number line?
Answers
Answer:
9/80
Step-by-step explanation:
1/8 = 10/80
1/10 = 8/80
9/80 is fraction between 1/8 and 1/10
The common fraction which is halfway between 1/8 and 1/10 on a number line is 9/80.
We are given that;
The two numbers 1/8 and 1/10
Now,
A fraction represents a part of a number or any number of equal parts.
To find the common fraction that is halfway between 1/8 and 1/10 on a number line, we need to find the average of the two fractions. To do this, we need to add the fractions and divide the sum by 2. To add the fractions, we need to find a common denominator for them. The least common multiple of 8 and 10 is 40, so we can multiply the first fraction by 5/5 and the second fraction by 4/4 to get equivalent fractions with the same denominator:
1/8 + 1/10 = (1/8)(5/5) + (1/10)(4/4) = 5/40 + 4/40
Now we can add the fractions by adding the numerators and keeping the denominator:
5/40 + 4/40 = (5 + 4)/40 = 9/40
To divide this fraction by 2, we can multiply it by the reciprocal of 2, which is 1/2:
(9/40) / 2 = (9/40) x (1/2) = (9 x 1)/(40 x 2) = 9/80
Therefore, by fraction the answer will be 9/80.

Answer:
[tex] V_{weights} =1,243 \: cm^3 [/tex]
Step-by-step explanation:
Radius of weight [tex] r_1=\frac{20}{2}= 10 \:cm[/tex]
Radius of hole [tex] r_2=\frac{2}{2}= 1 \:cm[/tex]
Height of weight as well as hole (h) = 2 cm
Volume of weights = (Volume of one weight - volume of hole)
[tex] \therefore V_{weights} = 2 (\pi r_1^2 h - \pi r_2^2 h)[/tex]
[tex]\therefore V_{weights} = 2 \pi (r_1^2 - r_2^2 )h[/tex]
[tex]\therefore V_{weights} = 2 (3.14)(10^2 - 1^2 )2[/tex]
[tex]\therefore V_{weights} =12.56(100 - 1 )[/tex]
[tex]\therefore V_{weights} = 12.56(99)[/tex]
[tex]\therefore V_{weights} =1,243.44[/tex]
[tex]\therefore V_{weights} \approx 1,243 \: cm^3 [/tex]

Consider a cylinder with height h=3x-4 and radius r=3x+2 Determine a simplified expression for the ratio of the volume of the cylinder to its surface area. Make a sketch of the cylinder
Answers
Step-by-step explanation:
Given that,
The height of the cylinder, h = 3x-4
The radius of the cylinder, r = 3x+2
The volume of the cylinder is :
[tex]V=\pi r^2 h[/tex]
The surface area of the cylinder is :
[tex]A=2\pi r(r+h)[/tex]
The ratio of the volume of the cylinder to the surface area of the cylinder is :
[tex]\dfrac{V}{A}=\dfrac{\pi r^2h}{2\pi r(r+h)}\\\\\dfrac{V}{A}=\dfrac{rh}{2(r+h)}[/tex]
Put all the values,
[tex]\dfrac{V}{A}=\dfrac{(3x+2)(3x-4)}{2(3x+2+3x-4)}\\\\\dfrac{V}{A}=\dfrac{(3x+2)(3x-4)}{2(6x-2)}[/tex]
Hence, this is the required solution.
