What is the area of this circle with center c, rounded to the nearest tenth?

Answers

Answer 1

Answer:

The equation for the area of a circle is:

A = \pi r^{2}

The diameter of the circle is 44cm, to get the radius you divide the diameter by 2, or the radius is half of the diameter

\frac{d}{2} = r

\frac{44}{2} = r

22 = r

Now that you have r, you can plug it into the equation

A = \pi (22)^{2}

A = \pi (484)

A = 1520.5 cm²

The answer would be closest to the first multiple choice answer

David can finish painting the room in 6 hours, and his elder brother Antony can finish it in 4 hours. If both brothers paint the room together, how many hours will it take them?

Answers

Both brothers paint the room together, it will take 2 hours 22 minutes.

Given that,

David can finish painting the room in 6 hours,

And his elder brother Antony can finish it in 4 hours.

We have to determine,

If both brothers paint the room together, how many hours will it take them.

According to the question,

David can finish painting the room in 6 hours,

And his elder brother Antony can finish it in 4 hours.

The combined time is given by the following formula.

Therefore,

For both brothers paint the room together, how many hours will it take them,

Taking reciprocal of both brothers time.

Then,

$(1)/(6) + (1)/(4) = (1)/(t) \n\n(2+3)/(12) = (1)/(t) \n\nt = (12)/(5) \n\nt = 2.4$

Which is equals to 2 hours 22 minutes.

Hence, Both brothers paint the room together, it will take 2 hours 22 minutes.

Answer:

Step-by-step explanation:

1/6+1/4=5/12

5/12 of the job is done in 1 hour

5/12+5/12= 10/12

so 10/12 of the job is done in 2 hours

and then simplify 5/6 so then add 1/6

so it is done in 2 hours and 24 minutes

What is the volume of a hemisphere with a radius of 3 cm, rounded to the nearest tenth of a cubic centimeter?

Answers

The Volume of sphere whose radius is 3 cm = 113 $cm^(3)$ (rounded to the nearest tenth)

Volume= 113 $cm^(3)$

What is Volume of sphere?

The volume of a sphere = 4/3 r³, where r is the radius of the sphere.

Volume of sphere = $(4)/(3) * \pi* r^(3)$

= $(4)/(3) * 3.14* (3)^(3)$

= 4 x 3.14 x 9

=113.04 $cm^(3)$

≈ 113 $cm^(3)$ (rounded to the nearest tenth)

Final answer:

The volume of a hemisphere with a radius of 3 cm is approximately 56.6 cm³ when rounded to the nearest tenth of a cubic centimeter. This is calculated by halving the volume of a sphere with the same radius.

Explanation:

Calculating the Volume of a Hemisphere

The question asks for the volume of a hemisphere with a radius of 3 cm. The formula for the volume of a sphere is V = (4/3)πr³, and since a hemisphere is half of a sphere, the formula adapts to V = (1/2)(4/3)πr³. Using a radius (r) of 3 cm, we get V = (1/2)(4/3)π(3 cm)³.

Let's calculate the volume step by step:

First, calculate the volume of the full sphere using the radius of 3 cm: V = (4/3)π(3³) cm³
Compute the result: V = (4/3)(π)(27) cm³ = (36π) cm³
Since we want the volume of the hemisphere, we divide this number by 2: V = (36π/2) cm³ = (18π) cm³
Finally, we approximate π to 3.142 and round to the nearest tenth: V ≈ 18(3.142) cm³ ≈ 56.6 cm³

Therefore, the approximate volume of the hemisphere is 56.6 cm³, when rounded to the nearest tenth of a cubic centimeter.
