Answer:
r = 1.4927053303605 cm
C = 9.3789441996695 cm
A = 7 cm²
Step-by-step explanation:
r = radius
C = circumference
A = area
π = pi = 3.1415926535898
√ = square root
27 + 14 + 9 = 50.
so 27/50 would equal 270 pizzas. Hope it helps!

Answer:
Equations
Step-by-step explanation:
16:
7 · (-3) = -21
-3 · 7 = -21
-21 ÷ 7 = -3
-21 ÷ (-3) = 7
17:
-4 · (-5) = 20
-5 · (-4) = 20
20 ÷ (-4) = -5
20 ÷ (-5) = -4
18:
1.5 · (-3) = -4.5
-3 · 1.5 = -4.5
-4.5 ÷ 1.5 = -3
-4.5 ÷ (-3) = 1.5
This is 7th grade?
