PLEASE HELP FINDING CIRCUMFERENCE AND AREA OF A CIRCLE

The circumference of the circle is 28.26 m.

The area of the circle is 63.585 .

Step-by-step explanation:

To solve for the circumference of the circle, start by using the circumference formula of a circle, which is . However, 3.14 will be used instead of for this formula.

First, the radius of the circle needs to be found. To find the radius of the circle, divide the diameter by 2 because the radius equals half of the diameter. The radius is 9 m divided by 2, which equals 4.5 m.

Next, plug in the radius into the formula, and the formula will look like . Then, solve the equation, and the answer will be 28.26 m.

To solve for the area of the circle, start by using the area formula of a circle, which is . However, 3.14 will be used instead of for this formula.

For the area, plug the radius into the formula, and the formula will look like . Then, solve the equation, and the answer will be 63.585 .

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.

hope it !

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
