Circumference=2piradius
Using that, you need to find the radius (which is one half of the diameter) 72/2=36
That is when you can plug the radius in: Circumference=2pi36
2*36=72. 72*pi is 72pi, or if you want to use 3.14, 72*3.14=226.08
Answer:
1. 5
2. 4
3. 20
4. 10
Step-by-step explanation:
You count the units of the length and width of the triangle which is also the same for the rectangle and l*w=the area (length is the longer side).
Halve the area of the rectangle to find the area of the triangle.
P = age of Peter and S = Sylvia's age.
We will first decipher "four years prior Peter was three times as old as Sylvia." This can be composed P = 4 + 3*(S-4).
Next, we interpret "in 5 years the total of their ages will be 38 years" as (P + 5) + (S + 5) = 38.
Presently we have two questions (P and S) and two conditions, so we are prepared to settle. We substitute our first condition for P into our second condition:
(4+3*(S-4)+5) + (S+5) = 38
9 + 3S - 12 + S + 5 = 38
2 + 4S = 38
4S = 36
S = 9.
Substitute this once more into the main condition to discover P = 4+3*(S-4) = 4+3*(9-4) = 4+15 = 19.
Answer:
8,11,14,17,20,23,26
Step-by-step explanation:
Q = 3n+ 5
an=3n+5
a1=3(1)+5=8
