31.4 cm
Step-by-step explanation:
the radius is 5 so the diameter is 10 so you'll have to multiply 3.14 by 10 not 5
Answer:
160 cm × 120 cm
Step-by-step explanation:
this means 1 cm turns into 20 cm.
so, 8 cm × 6 cm becomes
8×20 = 160 cm × 6×20 = 120 cm
We use 2 different rules here:
1) sum of angles in a triangle is equal to 180 degrees
2) when a triangle side is a diameter of the circle, then angle opposite to diameter is equal to 90 degrees.
so from 2) we know that B= 90
then from first one:
sum of angles = 180 = 90 + (3x + 6) + x = 96 + 4x
so 180 - 96 = 4x
so x = 84/4
x = 21
so answer is
A= 3x+ 6 = 63 + 6 = 69
B = 90
C = 21
Answer:
I think it's "C"
Step-by-step explanation:
Because a function is the independent variable to the dependent variable... Since, the cost relies on the weight, the cost is dependent. While, the weight is independent. I don't know if I'm right, I kinda suck at math
