kirill [66]3 years ago

Answer:

<h3>The answer is option B</h3>

Step-by-step explanation:

Area of a circle = πr²

where

r is the radius of the circle

From the question

Area = 154cm²

To find the radius substitute this value into the above formula and solve for the radius

That's

154 = πr²

Divide both sides by π

We have

{r}^{2}  =  \frac{154}{\pi}

Find the square root of both sides

Thats

r =  \sqrt{ \frac{154}{\pi} }

r = 7.0014086

We have the final answer as

radius = 7.0 cm

Hope this helps you

Special right triangles: what is the value of x? enter your answer in the box.
tiny-mole [99]
I think you meant to add more to your question (posting the specific problem).
In general, one special right triangle is the <span>45°-45°-90° triangle, in which both legs are congruent and the hypotenuse = √2 * the length of the leg. if you happen to not have the length of the leg, the formula for finding the leg is:  leg = hypotenuse / √2

Another special right triangle is the </span><span>30°-60°-90° triangle. With this kind of triangle the length of the hypotenuse is twice the length of the shorter leg. The length of the longer leg is √3 times the length of the shorter leg.
hypotenuse = 2 * shorter leg
longer leg = √3 * shorter leg</span>

Together, teammates Pedro and Ricky got 2680 base hits last season. Pedro had 276 more hits than Ricky. How many hits did each p
galina1969 [7]

Answer:

Ricky it is 1,202

And for Pedro = 1,202 + 276 = 1,478

Step-by-step explanation:

The computation is shown below:

Let us assume the ricky be x

So pedro be x + 276

Now the equation is

x + x + 276 = 2680

2x + 276 = 2680

2x = 2680 - 276

2x = 2404

x = 1,202

For Ricky it is 1,202

And for Pedro = 1,202 + 276 = 1,478
