Answer:

22,000 miles

Step-by-step explanation:

Circumference of a circle: 2πr (r is the radius)

Substitute the length of the radius given, which is 3500. Also, substitute the approximate value of π, which is 3.14.

Circumference = 2 * 3.14 * 3500

Circumference = 21980

This rounds to about 22,000, so the answer is 22,000 miles.

I hope this helps! Feel free to ask any questions!

Answer: 22,000 miles

Step-by-step explanation:

Circumference of circle = 2πr

2 × 22/7 × 3500

22/7 × 3500 = 11000

2 × 11000 = 22000

The circumference would be 22,000 miles.

Circumference of circle = 2πr

2 × 3.14 × 3500

6.28 × 3500 = 21,980

21980 to the nearest 1000 is 22000

The circumference would be approximately 22,000 miles.

A person invested $2,500 in an account growing at a rate allowing the money to

sveta [45]

Answer:

Step-by-step explanation:

A person invested $2,500 in an account growing at a rate allowing the money to double every 11 years. How long, to the nearest tenth of a year would it take for the

value of the account to reach $3,800?

The formula for exponential growth given as:

A(t) = Ao (1/2)^t/t½

A(t) = Amount after time t = $3,800

Ao = Initial amount invested = $2500

t = Time in years

t½ = Time it takes to double = 11 years

Hence,

3800 = 2500(1/2)^t/11

Divide both sides by 2500

3800/2500 = 2500(1/2)^t/11/2500

A washer and a dryer cost $763 combined. The washer costs $63 more than the dryer. What is the cost of the dryer?

Leni [432]

Answer:

$350

Step-by-step explanation:

w +d = 763

d + 63 = w

-w + d = -63

2d = 700

d = 350

The radius of a circular plate is 12 centimeters. What is the area, in square centimeters, of this plate? Write your Anwer using

lesya [120]

Answer:

The area of circular plate is <u>144π square centimeters</u>.

Step-by-step explanation :

<h3><u>Solution</u> :</h3>

Here, we have given that the radius of circular plate is 12 centimeters.

So, finding the area of circular plate by substituting the values in the formula :

$\longrightarrow{\pmb{\sf{Area_{(Circle)} = \pi{r}^{2}}}}$

$\longrightarrow{\sf{Area_{(Circle)} = \pi{(12)}^{2}}}$

$\longrightarrow{\sf{Area_{(Circle)} = \pi{(12 \times 12)}}}$

$\longrightarrow{\sf{Area_{(Circle)} = \pi{(144)}}}$

$\longrightarrow{\sf{Area_{(Circle)} = \pi \times 144}}$

$\longrightarrow{\sf{Area_{(Circle)} = 144\pi}}$

$\star{\underline{\boxed{\frak{\purple{Area_{(Circle)} = 144\pi\: {cm}^{2}}}}}}$

Hence, the area of circular plate is 144π square centimeters.
