Answer:
33.49cm³
Step-by-step explanation:
Volume of sphere =4/3πr³
diameter = 4cm
radius = diameter/2 = 4/2 = 2
Volume of sphere =4/3πr³= 4/3 x 3.14 x 2³ = 4/3 x 3.14 x 8 = 4/3 x 25.12 = 4x25.12/3 = 100.48/3 = 33.49cm³
19 and 3 are both prime numbers, and the difference is 16.
All you would need to to is do 13+23= 33 to get the total amount of people who dropped out, then do 72 ( the number in the beginning and subtract 33 from it because those are the people who dropped out so 72-33=39. 39 people finished the race.
<u>Given</u>:
Given that the radius of the figure is 6 units.
We need to determine the area of the shape.
<u>Angle of the shape:</u>
The angle of the shape is given by
Hence, the angle of the shape is 270°
<u>Area of the shape:</u>
The area of the shape can be determined using the formula,
Substituting r = 6, we get;
Simplifying, we get;
Thus, the area of the shape is 84.78 square units.
For starters, find the common change in the terms, in this case each goes down by 3. This lets you know you're gonna have a -3n in your equation as each term decreases by 3. Your equation should be in f(n)=c+rn form, with r being change in f(n), or -3 in this case. This gives you f(n)=c-3n. Now, solve for c, add 3n to both sides to get f(n)+3n=c. Plug in your n of 1 and f(n) of 20 to get c=20+3(1)=23. Plug in your c to your f(n) formula to get f(n)=23-3n as your f(n) function.
