Acircle has a radius of 17. approximately what is the area of the circle

A=907.92

Step-by-step explanation:

A=πr^2

A=π(17)^2

A=approximately 907.92

907.46

Step-by-step explanation: To find the area of a circle, start with the formula for the area of a circle.

Area = πr²

In this problem, we are given the radius of the circle which is 17 so we can plug 17 into our formula for the radius.

Area = (π) (17)²

Next, remember that 17² is equal to 17 × 17 which is 289.

Therefore, our exact answer is 289π.

Now, remember that π is approximately equal to 22/7 or 3.14 so we can estimate the area of the circle by plugging 3.14 in for π.

(289) (3.14) = 907.46

Therefore, the estimated area of the circle is 907.46.

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
