Step-by-step explanation:
we first find area of the whole shape outer core which is
we use the fomulae of a circle 22/7 represent pie
=1/2 *22/7*8,5
=13,36
then we find the inner core of the shape which is
1/2*22/7*5,5
=8,64
then we substracte to get the shaded part 13,36-8,64
=4,72cm
3 is, since you can divide both 6 and 3 by 3.
Simply look at the factors for each,
1, 3 for 3
1, 2, 3, 6 for 6.
Answer:
x> 30
Step-by-step explanation:
+ First, is the inequation 3x - 52 > 28.
+ If Yes, so we can solve:
3x - 52 > 28
3x - 52 + 52 > 28 +52
3x > 90
3x/3 > 90/3 (divide both sides by 3>0)
x > 30
1a.
you still have
k=C+273.15
k-C= 273.15 as related equations
b. at C=23
k=23+273.15 = 296.15
c. 25°C in kelvin = 25+273.15 = 298.15
so 300K is greater than 25°C
