Answer: 7 significant figures
Step-by-step explanation:
There are seven numbers.
If in the future had any 0s at the very beginning or at the end they wouldn't count example: 010.659220
n is a number
"the sum of <span>a number and twelve" is (n+12)
"</span><span>Six times the sum of a number " is 6(n+12)
6(n+12)=40
6n+72=40
6n=40-72
6n= - 32
n=-32/6 = -16/3 or -5 1/3</span>
Answer:
33.53
Step-by-step explanation:
OB is a radius of the circle, and OC is also a radius of the circle, so both are equal length. That makes ΔOBC an isosceles triangle.
If we cut ΔOBC in half, the angle formed is 125° / 2 = 62.5°.
Therefore:
sin 62.5 = (x/2) / 18.9
x = 37.8 sin 62.5
x ≈ 33.53
Answer:
Step-by-step explanation:
Formula
V = (1/3) pi * r^2 * h Substitute the givens into the formula
Givens
V = ?
pi = 3.14
r = 3 in
h = 18 in
Solution
V = 1/3 * 3.14 * 3 * 3 * 18
V = 169.56
Answer
V = 169.56 in^2
