A large pizza has diameter 36 cm and a medium pizza has diameter 30 cm. What is the difference in area of the pizzas? Round your

vladimir1956 [14]

Answer:

311 $cm^{2}$

Step-by-step explanation:

Taking a pizza to be a circle

Area of big pizza be x abd are of small pizza be y

hence difference = x-y

Area of a circle = $\pi r^{2}$ where r is the radius

taking $\pi$ to be 3.14

hence area x = 3.14 ( $\frac{36}{2}$ * $\frac{36}{2}$ ) = 1017.36

Area y = 3.14 ( $\frac{30}{2}$ * $\frac{30}{2}$ )= 706.5

x-y = 1017.36- 706.5 =310.86 $cm^{2}$

310.86 $cm^{2}$

Can someone help me with system of equations?

nignag [31]

2x + y = 350
x + 2y = 475
3x + 3y = 825
x + y = 275
x = 275 - y
(plug back into first equation)
2(275 - y) + y = 350
550 - 2y + y = 350
550 - y = 350
-y =-200 or y = $200 (dog)
therefore, x = $75 (cats)
Check
2(75) + 200 = 350
75 + 400 = 475
HAPPINESS! :)
