You would multiply 10 times \pi (3.14) $you would multiply 10 times \pi and get 31.40 cm squared$ and get 31.40 cm squared

Radius= 1/2 diameter= 1/2(10)= 10/2= 5

Circle Formula for Area= πr^2
C= πr^2

= (3)(5)^2
square 5; when squaring, multiply the number by itself one time

= 3(5*5)
= 3(25)
= 75 cm^2

ANSWER: The approximate area is 75cm^2 (using 3 for π).

Hope this helps! :)

Katarina [22]

Answer:

So, the relationship with i hours as the indecent variables would be

Serena can't paint 400 square feet of wall space of wall space in 3.5 hours.

Step-by-step explanation:

Since we have given that

Area that she can paint = 60 square feet

Time taken = half hour = 30 minutes = 0.5 hours

Using "Unitary method, we get that

In 0.5 hours, she can paint = 60 square feet

In 1 hour, she can paint =

In i hours, she can paint =

Let the total area she can paint be 'y'.

So, the relationship with i hours as the indecent variables would be

Now, Can Serena paint 400 square feet of wall space i. 3.5 hours

We put y = 400 and i = 3.5 hours to check whether it is equal or not.

Hence, Serena can't paint 400 square feet of wall space of wall space in 3.5 hours.

Rectangle ABCD was dilated to create rectangle A'B'C'D. Triangle A B C D is dilated to form triangle A prime B prime C prime D.

MArishka [77]

Answer:

AB=6 Units

Step-by-step explanation:

Given the following lengths of rectangle ABCD and its dilation A'B'C'D' respectively

A'B' = 15 Units
B'C' = 9.5 Units
BC = 3.8 units

We are to determine the length of AB. To do this, we first determine the dilation factor.

$D$ilation Factor =\dfrac{B'C'}{BC} =\dfrac{9.5}{3.8} =2.5$

Therefore:

$\dfrac{A'B'}{AB} =2.5\\\\\dfrac{15}{AB} =2.5\\$Cross multiply \\ 2.5 AB =15 \\AB=15 \div 2.5\\$Therefore, AB=6 Units$

Answer:

$y=\frac{6}{5}x-24$

Step-by-step explanation:

$Since\ the\ yellow\ points\ are\ \left(20,0\right)and\ \left(70,60\right)$
$so,\ set\ the\ equation\ of\ this\ is\ y=mx+b$
$\rightarrow0=m\times20+b$
$60=m\times70+b$
