7.19%
Step-by-step explanation:
let i be the effective rate
<span>37.7
The formula is </span>V=<span><span>π<span>r^2*</span></span><span>h/3, and since r is 4/2, you multiply it by </span></span><span><span>π and then multiply it h/3, which is 9/3, so ((2*3.14)*3)= 37.7.</span></span>
Answer:
Your answer choice is correct.
Step-by-step explanation:
The length of the semicircle is ...
s = π·r = π(4 in)
The three sides of the rectangular section total ...
9 in + 8 in + 9 in = 26 in
The sum of these lengths make up the perimeter of the figure:
P = 4π in + 26 in
P = (4π +26) in
Anything without a variable in front.
In other words, the constants are -3.7 and 1/3
The perimeter is just adding all the sides together.
a.) 180 = 40 + 40 + x + x
180 = 80 + 2x Subtract 80 on both sides
100 = 2x Take 1/2 of 100 to get x
x= 50cm
b.) 1000 = 150 + 150 + x + x
1000 = 300 + 2x Subtract 300 on both sides
700 = 2x Take 1/2 of 700 to get x
x = 350
