We have to calculate the pizza´s area.
r=radius
Area (circle)=π*r²
diameter=30 cm
radius=diameter/2=30 cm/2=15 cm
Area(pizza)=π*(15 cm)²=225π cm²≈706.86 cm².
solution: 706.86 cm²
        
             
        
        
        
The solution to the equation is x < 1.25
        
             
        
        
        
Answer:
a) $ 22x -9 
b) 44x - 18 
c) $319
Step-by-step explanation:
Given that,
number of $1 bills wyatt has = (2x-1) 
number of $5 bills wyatt has = (4x + 2)
The total amount of money that Wyatt has in terms of x
(2x - 1) + 5(4x + 2)
= 2x - 1 + 20x + 10
= $ 22x -9  
The number of pens that Wyatt can buy if each pen costs 50 cents
$(22x - 9) * 100 
= 2200x - 900 cents / 50 
= 44x - 18
 If x = 21, amount of money Susan will have now if Wyatt gives her half the number of five dollar bills that he has
 ( 5 (4x + 2) / 2) + ( 2 (21) - 1) 
= 215 + 41
= 256
As we know that Susan has $3x more than Wyatt 
So,
256 + 3x 
= 256 + 3(21)
= $319

Answer:
Solution given:
length[a]=3cm
base(b)=7cm
hypotenuse [c]=?
we have
by using Pythagoras law
a²+b²=c²
3²+7²=c²
c=√58=7.61m
<u>the length of the hypotenuse is 7.61</u><u> </u><u>o</u><u>r</u><u> </u><u>7</u><u>.</u><u>6</u><u> </u><u>o</u><u>r</u><u>8</u><u>m.</u>
