The pythagoream theorem (not sure if I spelled that right...lol): a^2 + b^2 = c^2......where c is the hypotenuse and it is the longest side

5^2 + 12^2 = 13^2
25 + 144 = 169
169 = 169....(correct)...so it is a right triangle

Answer:

RADIUS

==================================

PROBLEM

Mary’s bicycle wheel has a circumference of 226.08 cm². What is its radius?

SOLUTION

We can solve this problem using the circumference formula in which π stands for ( 3.14 ), C stands for circumference itself and r stands for radius.

\bold{Formula \: || \: C = 2πr}Formula∣∣C=2πr

\tt{226.08 = 2(3.14) r}226.08=2(3.14)r

'Now to find the radius,Substitute 226.08 for c which is circumference in the formula.

\begin{gathered} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \tt{C = 2πr} \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \tt{226.08 = 2(3.14)\red{r}} \\ \\ \: \: \: \: \: \: \: \: \large \tt{ \frac{226.08}{6.28} = \cancel\frac{6.28 \red{r}}{6.28} } \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \boxed{\tt\green{C = 36}}\end{gathered}

C=2πr

226.08=2(3.14)r

6.28

226.08

=

6.28

6.28r

C=36

To check:

\begin{gathered} \small\begin{array}{|c|}\hline \bold{circumference }\\ \\ \tt{C = 2πr} \\ \tt{C = 2(3.14) (36\:cm) } \\ \tt{C = 2(113.04\:cm) } \\ \underline{\tt \green{C = 226.08\:cm }} \\ \hline \end{array} \end{gathered}

circumference

C=2πr

C=2(3.14)(36cm)

C=2(113.04cm)

C=226.08cm

FINAL ANSWER

If Mary's Bicycle has a circumference of 226.08 cm then the radius is 36.

\boxed{ \tt \red{r = 36}}

r=36

How many tiles of dimension 22.5 cm x 10 cm x 7.5 cm can be painted if the paint is sufficient for the surface area 2812.50 m2 (
fenix001 [56]

Answer:

30 000 tiles

Step-by-step explanation:

Firstly convert the dimensions into metres

Then find the total surface area for one tile...in its....;

T.Surface area = 2(0.225 × 0.1) + 2(0.1 × 0.075) + 2(0.225 × 0.075)

Total surface area of one tile = 0.09375m^2

Then divide it into the surface area that the paint can be applied to....

2812.50 ÷ 0.09375 = 30 000 tiles
