It's easy, just plug the values requested in n & solve:
A(n)=4+(n-1)(8)
second, n=2 ==> A₂ = 4 +(2-1)(8) = 12
fourth, n=4 ===> A₄ = 4 +(4-1)(8) = 20
tenth, n=10 ==> A₁₀ = 4 + (10-1)(8) = 72
This an Arithmetic progression:
with 1st term a₁ =4 & d ( common difference) =8
Answer:
Below in bold.
Step-by-step explanation:
If I have interpreted the question correctly it is:
3*3*3*3 *x*x*x*x = 34
81 x^4 = 34
x^4 = 34/81
x = +/- (⁴√34) / 3 is the exact answer , or:
x = +/- 0.805 to nearest thousandth.
Answer:
Both the radius and height of the cylinder are 2.48 cm.
Step-by-step explanation:
V = π r2 h
(where r is the radius and h is the height.)
However, in the problem statement, we were told that the radius equals the height or "r = h"
So, we can rewrite the above equation as:
V = π r2*r = π r3
Now we just have to solve for r
r3 = V/π
r = (V/π)1/3
r = (48/π)1/3=2.48 cm
