What is the area of a circle with a diameter of 18.2 cm? use 3.14 for TT and round your final answer to the nearest hundredth.

the area is ___ square cm.​

260.0234 cm

Step-by-step explanation:

The formula for area of a circle is π r².

Since the radius is half of the diameter, we must divide the diameter by 2.

18.2/2 = 9.1

Next, we must multiply 9.1 x 9.1.

This gives us 82.81

Now we must multiply 82.81 by pi (3.14).

82.81 x 3.14 = 260.0234

Therefore, the area of the circle is 260.0234.

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
