Answer:120cm
Step-by-step explanation:
10cm x 12cm=120cm
800 people because when you try to find the number of people, x, you do cross multiply. So it will be 520/x = 65/100, next you multiply 520 by 100, then divide that by 65 to get 800 people
Answer:
A = 27π units²
Step-by-step explanation:
Note that a central angle of 120 degrees corresponds to 1/3 of a full circle.
The area of the full circle is A = πr², or A = π(9 units)² = 81π units², and so
the area of the sector in question is 1/3 of that, or A = 27π units²
B. ratio = 12:50
12/2=6 and 50/2=25
it cannot be broken down more after this is done.
so your answer is b
Answer:
x=39°
Step-by-step explanation:
the tangent from the diameter is 90°
x+90+51=180 sum of interior angle of the triangle is 180
x=180-90-51=39°
