Answer:
1330.5 cm³
Step-by-step explanation:
To find the volume you want to find the area of the circle and then times this by 14 which is the length of the shape
Area of circle = πr²
11 = the diameter so 5.5 = radius
5.5² x π = 121/4 π
times this by 14 to get 1330.464489 cm³
to 1dp = 1330.5 cm³
Answer:
1330cm³ (rounded to 3 s.f.)
Step-by-step explanation:
The formula of finding the volume of a cylinder is: [tex]\pi[/tex] × r² × h
r is the radius of the cylinder, which is also half of the diameter.
You know the diameter is 11cm and the height (h) is 14cm.
Volume of cylinder = [tex]\pi[/tex] × (11÷2)² × 14
= [tex]\pi[/tex] × 5.5² × 14
= [tex]\pi[/tex] × 30.25 × 14
= 423.5[tex]\pi[/tex]
= 1330cm³ (rounded to 3 s.f.)

In September, Louise planted a tree. Every month, the tree Louise planted grew 2 inches. What would the constant of proportionality of the line be?
Answers
Answer:
1/2
Step-by-step explanation:
Tree grow 2 inches per month
Let :
Month = m ; height increase, h
m α h
m = kh
k = proportionality constant
Where ; m = 1 ; h = 2
1 = 2k
1/2 = 2k/ 2
k = 1/2
Answer:1/2
Step-by-step explanation:
Tree grow 2 inches per month
Let :
Month = m ; height increase, h

Pedro is getting balloons for his grandmother's birthday party. He wants each balloon string to be 12 feet long. At the party store, string is sold by the yard. If Pedro wants to get 52 balloons, how many yards of string will he need? 1 foot = 1 3 yard
Answers
Answer:
Total length of string required in yards [tex]8112[/tex] yards
Step-by-step explanation:
The length of the string attached with each balloon is equal to [tex]12[/tex] feet
In the party total number of balloon used is equal to [tex]52[/tex] balloons
The total length of the string required
Length of string used in one balloon * total number of balloons
[tex]= 12 * 52 = 624[/tex] feet
1 feet is equal to 13 yards
Total length of string required in yards [tex]13 * 624 = 8112[/tex] yards

Answer:
A
Step-by-step explanation:
∆ABC is similar to ∆DEF if and only if the ratio of their corresponding side lengths are the same.
Let's find out:
DE/AB = 10/5 = 2
EF/BC = 8/4 = 2
FD/CA = 12/6 = 2
The ratio of their corresponding side lengths are equal, therefore, ∆ABC is similar to ∆DEF based on the SSS Similarity Theorem.

Step-by-step explanation:

Diameter of circle, d = 5.6 cm[tex] \\ [/tex]
[tex] \Large \underline{\tt To \: Find} :[/tex]
Circumference = ?[tex] \\ [/tex]
[tex] \Large \underline{\tt Solution} :[/tex]
As, we have diameter of circle is 5.6 cm and radius is half of diameter.
[tex] \tt : \implies Radius, r = \dfrac{d}{2}[/tex]
[tex] \tt : \implies Radius, r = \dfrac{5.6 \: cm}{2}[/tex]
[tex] \tt : \implies Radius, r = \dfrac{\cancel{56} \: cm}{10\times \cancel{2}}[/tex]
[tex] \tt : \implies Radius, r = \dfrac{28 \: cm}{10}[/tex]
[tex] \tt : \implies Radius, r = 2.8 \: cm[/tex]
[tex] \\ [/tex]
Now, for Circumference :
[tex] \Large \underline{\boxed{\bf{Circumference = 2\pi r}}}[/tex]
[tex] \tt : \implies Circumference = 2 \times \dfrac{22}{7} \times 2.8 \: cm[/tex]
[tex] \tt : \implies Circumference = \dfrac{44}{\cancel{7}} \times \dfrac{\cancel{28}}{10} \: cm[/tex]
[tex] \tt : \implies Circumference = 44 \times \dfrac{4}{10} \: cm[/tex]
[tex] \tt : \implies Circumference = \dfrac{176}{10}\: cm[/tex]
[tex] \tt : \implies Circumference = 17.6\: cm[/tex]

Hence, circumference is 17.6 cm.

Let x and y represent the measures of the two acute angles in the right triangle.
From your knowledge of right triangles, you know the two acute angles are complementary:
x + y = 90
The problem statement gives you another relation:
x = 2(y + 30) . . . . twice the sum ...
__
Solution
The second equation gives you an expression for x that can be substituted into the first equation.
(2(y +30)) + y = 90
3y +60 = 90 . . . . . . . . collect terms
3y = 30 . . . . . . . . . subtract 60
y = 10 . . . . . . . . divide by 3
x = 2(y +30) = 2(40) = 80
The two angles are 10° and 80°.
