Answer:
314.16 sq mm
Step-by-step explanation:
formula for area of a circle = pi(r^2)
if the diameter is 20mm then the radius is 10 mm
When you plug in pi(10mm^2) you get 314.16 sq mm
Answer:
Gradient = -3
• Parallel lines have the same gradient, therefore gradient, m is -3
• At point (0, -4)
y intercept is -4
6/x=27
times both sides by x
6=27x
divide both sides by 27
6/27=x
2/9=x
the missing number is 2/9
