Answer:
20/45
Step-by-step explanation:
4/8 = 2/4 = 1/2
4*3/8*3 = 12/24
but 20/45 = 4/9 So it is mot equivalent to 4/8
Answer:
one because it is cilinder
To solve this, you need to know the formula to find the circumference of the circle. It is: C=2(pie)r.
C is what you are finding.
Pie is 3.14(you already got that).
R is the radius.
There is not enough information to solve your problem, but I hoped the equation helped!
The sum of the interior angles of a triangle is always 180 degrees. Thus,
the sum of 31, x+4 and 3x+9 must be 180.
31 + x + 4 + 3x + 9 = 180, or 44 + 4x = 180
While it's not necessary, y ou could reduce this equation before solving for x:
11 + x = 45. Then x = 34 degrees.
The three angles are then:
31
34+4 = 38
3(34) + 9 = 111
Check: show that 31+38+111 = 180 (degrees)
