Area of a circle is:

A = pi * r^2

If the diameter is 10 feet, the radius will be half of that or 5.

So:

A = 3.14 * 5^2

Simplify exponent:

A = 3.14 * 25

Multiply:

A = 78.5

The area is πr².
The radius r is half the diameter. The diameter is 10 ft so the radius is 5 ft.

A=\pi \times 5^2=25 \pi

The area is 25π ft².

How to check division with multplication<br><img src="https://tex.z-dn.net/?f=3%20%5Ctimes%20292%20" id="TexFormula1" title="3 \
svetoff [14.1K]

Answer:  By cross multiplication.

Step-by-step explanation:  Given product is 3 × 292.

We know that after simple multiplication, we get  3 × 292 = 876.

Now, to check division with multiplication, either we need to divide 876 by 3 to get the answer 292,

or

we need to divide 876 by 292 to get the answer 3.

We will do that as follows -

\dfrac{876}{3}=292~~~\textup{and}~~~\dfrac{876}{292}=3.

Thus, doing cross-multiplication, we arrive at our conclusion.

Find the surface area of the cylinder
Alik [6]

Answer:

Surface Area = 282.6 cm²

Step-by-step explanation:

Formula: SA = 2\pirh + 2\pir²

SA = 2\pirh + 2\pir²

SA = 2(3.14)(5)(4) + 2(3.14)(5)

SA = 2(3.14)(5)(4) + 2(3.14)(25)

SA = 125.6 + 157

SA = 282.6 cm²

Donna is running around a track.It takes her 3 1/2 minutes to run 1/4 of a lap.If she keeps running at the same speed,how long w
meriva

Answer:

70 minutes

Step-by-step explanation:

3 1/2 ÷1/4= 14 ×5= 70

so you first make 3 1/2 to an improper fraction, then you find the greatest common denominator between 7/2 and 1/4 which is 4, so you multiple 7/2 by 2 and get 14/4 and divide that by 1/4 and get 14minutes now multiply that by 5 laps and receive 70 minutes.
