Find the number if:
Paraphin [41]

Answer:

162 and \frac{5}{2}

Step-by-step explanation:

To find the original number multiply by the reciprocal of the multiplier, that is

90 × \frac{9}{5} = \frac{810}{5} = 162

------------------------------------------------------------------------

Similarly

Change the mixed number into an improper fraction

5 \frac{5}{6} = \frac{35}{6} , then

\frac{35}{6} × \frac{3}{7} ( cancel 35 and 7 by 7 / cancel 6 and 3 by 3 )

= \frac{5}{2} × \frac{1}{1}

= \frac{5}{2}

A dinner plate has a circumference of 106.76 cm. What is the area of the dinner plate? Use = 3.14.
Sphinxa [80]
C=2pr,  r=c/(2p)

a=pr^2, using r found above we get:

a=p(c^2/(4p^2))

a=(c^2)/(4p), since c=106.76 and we approximate pi as 3.14

a=(106.76^2)/(4*3.14)

a=11612.2176/12.56 cm^2

a≈924.54 cm^2  (to nearest one-hundredth of a square cm)
