Answer:
A=640.88
Step-by-step explanation:
if the diameter is 12, the radius , r=12/2=6
we have r=6, h=11
Surface area, A= 2πrh+2π r^2
A=2*3.14*6*11+2*3.14*(6)^2=640.88
567 square mm
because 27*7 is 189 an times 3 because each side has 3 sides so it equals to 567 square mm! :)
Answer:
15
Step-by-step explanation:
I'J' is IJ with the scale factor of 5.
so (IJ) × 5= (I'J)
(IJ) × 5= 75
75 ÷ 5= 15
I am so sorry i did the math wrong in my head, the answer is 15 not 16.
Let the angle be x
complement 90-x
so the equation will be
3x = 90-x-14
3x+x = 90-14
4x = 76
x=76/4= 19
90-x= 90-19 =71
