Answer:

22in²

Step-by-step explanation:

According to the scenario, computation of the given data are as follows,

Circumference = 25 (1/7)

As we know,

Circumference of a circle = 2πr

By solving this we get

Radius (r) = 4in

Now. we can calculate the area by using following formula,

Area  = πr²

By putting the value, we get

Area = (22/7) × 4²

=  22/7 × 16

= 352÷16

Area = 22in²

Alborosie

Answer:

For children ages 2 to 5, limit screen time to one hour a day of high-quality programming. As your child grows, a one-size-fits-all approach doesn't work as well. You'll need to decide how much media to let your child use each day and what's appropriate.

Step-by-step explanation:

For kids aged 2 to 5, screen time should be limited to 1 hour per day, and parents should watch the programs with their child. Also, parents should have times when screens are turned off, and bedrooms should be media-free.

The product of two consecutive even integers is 440.. what are the positive and negative integers?
shutvik [7]

Positive integers are 20,22 and negative integers are -22,-20.

Step-by-step explanation:

Let,

2 positive integers are x, x+2

According to given statement;

x(x+2)=440\\x^{2}+2x=440\\x^{2}+2x-440=0\\x^{2}+22x-20x-440=0\\x(x+22)-20(x+22)=0\\(x+22)(x-20)=0\\Either,\\x+22=0\\x=-22\\Or,\\x-20=0\\x=20

If x=-22

Then,

x+2 = -22+2 = -20

Or,

x=20

x+2 = 20+2 = 22

Positive integers are 20,22 and negative integers are -22,-20.
