Answer:
308
Step-by-step explanation:
7x3x11=308
The word each means to multiply in math.
step 1 :
Because soccer ball is in the shape of sphere, we can use the formula of volume of a sphere to find volume of the soccer ball.
Write the formula to find volume of a sphere.
V = <span>4/3 · ∏r</span>³ ----- (1)
Step 2 :
To find the volume, we need the radius of the sphere. But, the diameter is given, that is 24 cm. So, find the radius.
r = diameter / 2
r = 24/2
r = 12
Step 3 :
Plug ∏ ≈ 3.14 and r = 12 in (1).
<span>V ≈ 4/3 </span>· 3.14 · 12³
Simplify.
<span>V ≈ 4/3 </span>· 3.14 · 1728
<span>V ≈ 7,234.6</span>
<span>Hence, the volume of the soccer ball is about 7,234.6 cubic cm. </span>
M < 1 = 140
m < 2 = 40
m < 2 + 90 + m < 3 = 180..(total of angles in a triangle are 180)
40 + 90 + <3 = 180
130 + <3 = 180
m < 3 = 180 - 130
m < 3 = 50
A) opposite angle from sin theta 30 is cosine theta 60
b) and the opposite angle from cosine theta 60 is sin theta 30
The order of operations is:
Parenthesis
Exponent
Multiplication
Division
Addition
Subtraction
So division comes first:
Now subtraction:
