the side of the square is 16cm so the diameter of the circle is 16cm
The radius of the circle is 8cm since the radius is half the diameter
To A=πr^2 in which r=8
so A=πr^2=π·82≈201.06193
Diameter = 16cm
QuestionArea of the circle
Way to do#Find the radius first to get the area
radius = diameter : 2
radius = 16cm : 2
radius = 8cm
#After that, find the area
Area = π × r²
Area = π × (8cm)²
Area = π × 64cm²
Area = 3.14 × 64cm²
Area = 200.96cm²
Noteπ (phi) = 22/7 or 3.14
r = diameter : 2
Area of circle = π ×r²
Perimeter of the circle = π×d
r = radius
d = diameter

Answer:
Height: 6.7 Length: 22
Step-by-step explanation:
Use Soh (sin(angle)=[tex]\frac{opposite}{hypotenuse}[/tex]) Cah (cos(angle)=[tex]\frac{adjacent}{hypotenuse}[/tex]) Toa (tan(angle)=[tex]\frac{opposite}{adjacent}[/tex])
Height:
You'd use sin so the equation is sin17=x/23 which is equal to (rounded) 6.7
Length:
You'd use cos so the equation is cos17=y/23 which is equal to (rounded) 22
*You always need to use a calculator when using sin, cos, and tan*

A party mix is made by adding nuts that sell for $2.50 per kg to a cereal mixture that sells for $1 per kg. How much of each should be added to obtain 40 kg if a mix that will sell for $1.30 per kg?
Answers
Answer:
40kg
Step-by-step explanation:
x + y = 60, y = 60 - x
x(2.50) + y(1) = 60(1.50)
Substitute:
2.50 x + 60 - x = 90
1.50x = 30
x = 20 kg
y = 40 kg

try to graph y=0.4 x
Answers
Answer: y = 0.4x in desmos
Step-by-step explanation:
Answer:
Not applicable.
Step-by-step explanation:
You could use Desmos as another person answered. However, if you are graphing by hand, simply choose two points and draw a straight line between them.
For example, you could pick x = 0 and x = 1. This gives you the two points (0, 0) and (1, 0.4)
Plot those two points and use a straight edge to draw a line between the two.
In case you are having trouble plotting (1, 0.4) since it is a decimal, try setting x = 5, you will get (5, 2) which should be much easier to graph.

the directions are : The table shows a proportional relationship between x and y. What is the unit rate of y per x.
Answers
Answer:
4
Step-by-step explanation:
To find the unit rate you can pick any row and do y divided by x
For example, x = 3 and y = 12 so you can do 12 / 3 = 4.
You could also use x = 5 and y = 20, so it would be 20 / 5 = 5
