You have 2+2 in each 2 there are 1's so
2=(1+1) 2=(1+1) =4
4=1+1+1+1
2+2=4
think of 2's as 1's when adding did you know 2x2= 4 as well.
Answer:
Express 23175.4 in standard form
Step-by-step explanation:
According to this chart, the area of a circle with a diameter of <span>2.2 m is
area=(pi)(r)^2=</span><span><span>(pi)(d/2)^2</span>
= (pi)(2.2/2)^2
= 1.21 (pi) m^2</span>
Answer:
50.265(correct to 5 significant figure)/ 16π
Step-by-step explanation:


=50.265(cor. to 5 sig.fig.)/ 16π
to find the arc length of a sector,we need to use πradius² times (sector's degree divided by 360degree).
