What is the circumference of a circle with a diameter of 5.8 inches? use 3.14 for π and round the answer to the nearest tenth. a) 9.1 inches b) 18.2 inches c) 36.4 inches d) 105.6 inches

B) 18.2 inches

Step-by-step explanation:

We know that the circumference of a circle is given by :-

Given : Diameter of a circle = 5.8 inches

Then, the circumference of the circle will be :-

Hence, the circumference of the circle = 18.2 inches

Option B.

Step-by-step explanation:

It is given that diameter of the circle is 5.8 inches.

Radius of the circle is

We need to find the circumference of the circle.

Circumference of a circle is

Substitute π= 3.14 and r=2.9 in the above formula, to find the circumference of the circle.

Round the answer to the nearest tenth.

The circumference of the circle is 18.2 inches. Therefore, the correct option is B.

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
