2. Delia and Beto left for school at the same time.
Tema [17]

<u>Answer:</u>

Beto will get to the school first.

<u>Step-by-step explanation:</u>

We are given that Delia lives 3/4 mile from school and walks at a pace of

16 minutes per mile.

So Delia takes \frac{3}{4} \times 16 = 12 minutes to reach school.

While Beto lives 3 1/2 miles from school  and bikes at a pace of 3 minutes per mile.

So Beto takes \frac{7}{2} \times 3 = 10.5 minutes to reach school.

Therefore, Beto will get to the school first.

Deon has a pizza with a diameter
OverLord2011 [107]

The square box is enough to fit the pizza with a diameter of 10 inches inside. Since the area of the square box is more than the area of the pizza, the pizza fits easily in the square box.

<h3>What is the area of the circle and the square?</h3>

The area of the circle is

Ac = πr² = πd²/4 sq. units

Where r is the radius and d is the diameter of the circle.

The area of the square is given by

As = s² sq. units

Where s is the length of the side of a square.

<h3>Calculation:</h3>

It is given that a pizza(in a circular shape) with a diameter d = 10 in is to be placed in a square box of the same length as the diameter of the pizza.

So,

The area of pizza is

Ap = Ac = πd²/4 sq. units

     = π(10)²/4

     = 25π

     = 78.54 sq. in

Then, the area of the square box with the length same as the diameter of the pizza is,

As = d²

    = 10²

    = 100 sq. in

Since the area of the square is more than the area of the pizza (100 sq. inch > 78.54 sq. inch), the pizza easily fits into the square box.
