Answer:
The meal consist 11 mozzarella sticks and 6 pizza rolls.
Step-by-step explanation:
We are given the following in the question:
Calories in mozzarella stick = 90
Calories in pizza roll = 80
Let x be the number of a mozzarella stick and y be the number of pizza rolls.
Total calories in meal = 1470
Thus, we can write the equation:
There are five more mozzarella sticks than pizza roll.
Thus, we can write the equation:
Solving the two equations, we get,
Thus, the meal consist 11 mozzarella sticks and 6 pizza rolls.
The area of circle is 254.34 square inches, if the circumference of a circle is 56.52 inches.
Step-by-step explanation:
The given is,
Circumference of a circle is 56.52 inches.
Step:1
Formula for circumference of circle is,
........................(1)
Where, r - Radius of circle
From the given,
C = 56.52 inches
Equation (1) becomes,
56.52 = 2 
(r)
56.52 = (2) (3.14) (r)
56.52 = 6.28 (r)
r = 9 inches
Step:2
Formula for area of circle,
............................(2)
Where, r - Radius of circle
From the given,
r = 9 inches
Equation (2) becomes,
= (3.14) (81)
= 254.34
Area of circle, A = 254.34 square inches
Result:
The area of circle is 254.34 square inches, if the circumference of a circle is 56.52 inches.
B
