The face of a clock has a circumference of 63 in. What is the area of the face of the clock?

Mathematics

Answer:

The area of the clock = 315.41\ inch^{2}

Step-by-step explanation:

We have been given the face of the clock that is 63\ in

So that is also the circumference of the clock.

Since the clock is circular in shape.

So 2\pi(r)=63\ inch

From here we will calculate the value of radius (r) of the clock that is circular in shape.

Then 2\pi(r)=63\ inch =\frac{63}{2\pi} = 10.02\ in

Now to find the area of the clock we will put this value of (r) in the equation of area of the circle.

Now \pi (r)^{2}=\pi(10.02)^{2}=315.41\ in^{2}

So the area of the face of the clock =315.41\ in^{2}

What is the volume of the cone to the nearest tenth?
Kisachek [45]

Answer:

366.5cm³

Step-by-step explanation:

1. Determine the height and radius of cone.

2. Using the formula for the volume of a cone input where there is an h and r.

3.Where it says Area of base, it is talking about the circular base and that you need to find its area. (π×r²), you already have the radius so you put it in the formula and solve (π×5²)

4. Once you have the area of the base you can now completely solve. Multiply ⅓×(78.54)×14

Franklin measured and labeled the angles of a triangle as shown. Jennifer says that at least one of his measures is incorrect. E
ioda

Answer:

see the explanation

Step-by-step explanation:

First way

we know that

The sum of the interior angles of a triangle must be equal to 180 degrees

so

In this problem

37+97+134 > 180

therefore

At least one of Franklin's measures is incorrect

Second way

we know that

A triangle can only have at most one obtuse internal angle.

In this problem the triangle has two obtuse internal angles

Remember that an obtuse angle is an angle greater than 90 degrees

therefore

At least one of Franklin's measures is incorrect

Suri makes $15 per hour and gets a weekly bonus of $25. Juan makes $14 per hour and gets a weekly bonus of $50. Is it possible f
Papessa [141]

Answer:

Yes. Suri and Juan can make the same amount of wages by working 25 hours in one week.

Step-by-step explanation:

Let each of them work x hours per week.

Suri makes $15 per hour, so in x hours Suri will make $ 15x. The total wages per week for Suri will be:

Total Wages = y = 15x + Bonus = 15x + 25

Juan makes $14 per hour, so in x hours Juan will make $ 14x. The total wages per week for Juan will be:

Total Wages = y = 14x + Bonus = 14x + 50

If they will make the same wages, their wages must be equal, i.e.

15x + 25 = 14x + 50

15x - 14x = 50 - 25

x = 25

This result shows us that if Suri and Juan work for 25 hours per week they will make the same amount of wages.
