Find the circumference of a circle that has a diameter of 4 m. Use 3.14 for pi. m

Arturiano [62]

Answer:

Step-by-step explanation:

The formula of a circumference of a circle:

$C=d\pi$

<em>d</em> - <em>diameter</em>

<em />

We have <em>d = 4m</em>.

Substitute:

$C=4\pi\ m$

Use 3.14 for π:

$C\approx4(3.14)=12.56\ m$

Helen's house is located on a rectangular lot that is1 1-8 miles by 9/10 mile.Estimate the distance around the lot

klemol [59]

Answer: The distance around the lot is given by

$4\frac{1}{20}\ miles$

Step-by-step explanation:

Since we have given that

Length of rectangular lot is given by

$1\frac{1}{8}\\\\=\frac{9}{8}\ miles$

Width of rectangular lot is given by

$\frac{9}{10}\ mile$

We need to find the distance around the lot.

As we know the formula for "Perimeter of rectangle":

$Perimeter=2(Length+Width)\\\\Perimeter=2(\frac{9}{8}+\frac{9}{10})\\\\Perimeter=2(\frac{45+36}{40})\\\\Perimeter=2\times \frac{81}{40}\\\\Perimeter=\frac{81}{20}\\\\Perimeter=4\frac{1}{20}\ miles$

Hence, the distance around the lot is given by

$4\frac{1}{20}\ miles$
