27/2=13.5(radius)

area: pi*r*r=

pi*13.5*13.5=

572.55526

rounded, 572.56

circumference: 2*pi*r(which is basically diameter times pi)

27pi=84.823

rounded, 84.82

PLEASE HELP WILL GIVE BRAINLIEST

Answer:

$\sqrt{0.02}$

Step-by-step explanation:

Let's first get the square root of 0.02...

≅ $0.1414$

Let's convert that to a percentage...

14.14%, which is less than 18%, so it checks out in that sense...

Now, let's convert 0.1414 to a fraction...

$\frac{707}{5000}$ , which is greater than $\frac{1}{8}$ (You can check this by multiplying $\frac{1}{8}$ by $\frac{625}{625}$ )

Therefore, $\sqrt{0.02}$ makes the inequality true.

Solve (x - 3)^2+7=97, where X is a real number. Round your answer to the nearest hundredth.

Eddi Din [679]

Answer:

x ≈ - 6.49, x ≈ 12.49

Step-by-step explanation:

Given

(x - 3)² + 7 = 97 ( subtract 7 from both sides )

(x - 3)² = 90 ( take the square root of both sides )

x - 3 = ± $\sqrt{90}$ ( add 3 to both sides )

x = 3 ± $\sqrt{90}$

Then

x = 3 - $\sqrt{90}$ ≈ - 6.49 ( to the nearest hundredth )

x = 3 + $\sqrt{90}$ ≈ 12.49 ( to the nearest hundredth )
