A = pi × r²
3.14 x 2²
3.14 x 4
A = 12.56636 ≈ 12.56
hopefully this helps u and if u know the formula to solve it, it is super easy
The mean is the average, which is the sum of all the numbers divided by the total numbers there are. I will add them up for you, and then work from there.
184 + 192 + 164 + 200 = 740.
There is 740cm total, but now we need to divide by how many students we have. We have 4 students total.
740/4 = 185.
Your average (mean) height of the students is 185cm.
I hope this helps!
Answer:
25
Step-by-step explanation:
Remember that multiplication and division will result in a positive number if no or two negative signs are present. So here, you ignore the negative signs.
All you really have to do is divide 50 by 2, which results in 25.
Answer:
Sₙ=3(1/2^n)
Step-by-step explanation:
Notice that in the given series that each term is being multiplied by 1/2, which is our common ratio. 3/2 is the first term because 3*1/2=3/2, so the expression that defines Sₙ is Sₙ=3(1/2^n)
