If a personal pan pizza (6 inches in diameter) has 600 calories, how many calories would you consume if you were to eat a large

Neko [114]

Answer:

2400 calories

Explanation:

given,

diameter of pizza,d₁ = 6 inches

calories of the 6 inches pizza = 600 calories

diameter of large size of pizza, d₂ = 12 inches

calories of the 12 inches pizza = ?

Area of the 6 inches pizza

A₁ = π x 3² = 9 π

Area of the 12 inches pizza

A₂ = π x 6² = 36 π

Ratio of 12 inch pizza to 6 inches

= $\dfrac{36\pi}{9\pi}$

= $\dfrac{4}{1}$

calories of the pizza

$\dfrac{x}{600}=\dfrac{4}{1}$

x = 2400 calories

Pizza of 12 inches is of calories is equal to 2400 calories

Andrews [41]

Momentum question. This is an inelastic collision, so

m1v1+m2v2=Vf(m1+m2)
Vf=(m1v1+m2v2)/(m1+m2)=[(120kg)(0m/s)+(60kg)(2m/s)] / (120kg+60kg)
Vf=120kg m/s / 180kg
Vf=0.67m/s

0.67m/s
