Answer:
one 18" pizza contains more pizza than 2 12" pizzas
Step-by-step explanation:
area of 12" pizza:
A = πr²
A = (3.14159)(6 in.)²
A = 113 in.²
two 12" pizzas have a total area of 226 in.²
area of 18" pizza:
A = πr²
A = (3.14159)(9 in.)²
A = 254 in.²
one 18" pizzas has a total area of 254 in.²
P.S. This problem is poorly worded. Above it states "... want to make sure I get the most pizza for my money." Since there is no indication of price for either option, two 12-inch pizzas or one 18-inch pizza, we cannot calculate what the most pizza for the money is. Below it states "which option should I choose to get the most pizza?" Here it no longer asks for most pizza for the money. Now it just asks for which option gives the most pizza.
The missing angle would be :
90°[right angle] + 45° = 135
180 - 135 = 45°
I took 135 away from 180 because angles in a triangle always add up to 180°
Answer:
point lies on circle
Step-by-step explanation:
Substitute the coordinates of the point into the left side of the equation and if equal to the right side then point lies on circle.
(4 - 1)² + (2 + 2)² = 3² + 4² = 9 + 16 = 25 = right side
Then point (4, 2 ) lies on the circle
Answer:
Step-by-step explanation:
Simply multiply 2m both sides:
A = (9+H)(2m)

Hey there,
Question : <span>A pigeon can fly at a speed of 84 kilometers per hour. How long does it take the pigeon to fly 7 kilometers?</span>
Answer :84 km = 1 hr
1 km = 1 / 84
= 1 / 84 hr
7 km = 1 / 84 x 7
= 1 / 12 hr
1 / 12 hr = 5 min
Hope this helps :D
