You have to divided 11 by 2 in order to get the radius
And you’ll get 5.5
r=5.5
h=12
Your formula is (1/3)(pi)(r^2)(h)
Answer:
$55.80
Step-by-step explanation:
First, find how much Janet saved by finding 1/5 of 15.50:
15.50/5
= 3.1
Find how much Rob saved by multiplying 3.1 by 12:
3.1(12)
= 37.2
Then, find the total saved amount by adding them all together:
15.50 + 3.1 + 37.2
= 55.8
So, they saved $55.80 in total
f(x) = 4^(x − 1) + 2
f (1)=3 f (2)=6
avarage rate=[ f (1) - f (2)]/(2-1)
=(6-3)/1
=3//
Answer:
$141,557.76
Step-by-step explanation:
Chao bought a boat for 160,000
The value of the boat reduces by 4% every year
Therefore the value of the most at the end of three years can be calculated as follows
= 100%- 4%
= 96%
= 160,000 × 96/100^3
= 160,000 × 0.96^3
= 160,000 × 0.884736
= 141,557.76
Hence the price of the boat after 3 years is 141,557.76
