<h3>Given :-</h3>

  • Area of Circle = 616 cm²

<h3>To Find :-</h3>

  • Radius of a circle = ?

<h3>Solution :-</h3>

☼︎ <u>Radius of the Circle</u>;

<h3>Using Formula:</h3>

\\ \red\bigstar {\underline{\boxed{\color{springgreen}{\textsf{ \textbf{ \: Area \: of \: circle= \:  \: π \:  r \: ² \: }}}}}} \\\\

<u>Putting values in the formula;</u>

\\  \sf \implies \: Area \:  =  \: \pi \: r \:  ^{2}  \\

\\  \sf \implies \: 616 \:  =  \:\frac{22}{7}  \times  \: r \:  ^{2}  \\

\\  \sf \implies \: 616 \: \times  \: \frac{7}{22}  \:  =  \: \: r \:  ^{2}  \\

\\  \sf \implies \:  \: \frac{ \:  \: 4312 \:  \: }{22}  \:  =  \: \: r \:  ^{2}  \\

\\  \sf \implies \:  \:  \cancel{\frac{ \:  \: 4312 \:  \: }{22}  }\:  =  \: \: r \:  ^{2}  \\

\\  \sf \implies \:  \:   \: 196 \:  \: =  \: \: r \:  ^{2}  \\

\\  \sf \implies \:  \:r \:  ^{2}  =    \: 196 \:  \:   \: \:  \\

\\  \sf \implies \:  \:r \:   =    \sqrt{ \: 196 \:  } \\

\\  \bf \implies \:  \:Radius  \:   =    14 \: cm \\

henceforth, the Radius of a circle is 14 cm ...!!

<u>Solution</u><u> </u><u>:</u>

  • Area of circle = 616 cm

We need to calculate the radius.

We know that :

  • A = πr^2

Here,

  • A is area
  • r is radius

Substituting values :

> 616 = (22/7) × r^2

> 616 = 22r^2 / 7

> 616 × 7 = 22r^2

> 22r^2 = 4312

> r^2 = 4312 / 22

> r^2 = 2156 / 11

> r^2 = 196

> r = 14

Tyina is buying 12 shirts for the drama club. She will choose a style for the blank shirts and then pay an additional charge of
tensa zangetsu [6.8K]

Answer:

Cost of each blank shirt is less than or equal to $ 5.5

Step-by-step explanation:

Let x denotes cost of each blank shirt.

Total number fo shirts bought by Tyina = 12

Amount charged for each shirt to have the club logo = $2.75

So,

Amount charged for 12 shirts to have the club logo = 12(2.75)=\$33

As Tyina cannot spend more than $99,

12x+33\leq 99

Now solve the inequality.

12x+33\leq 99\\12x\leq 99-33\\12x\leq 66\\x\leq \frac{66}{12}\\ x\leq 5.5

So,

Cost of each blank shirt is less than or equal to $ 5.5

What does b represent in the equation of a line in the form y=mc+b
Olin [163]

Do you mean y = mx + b instead of y = mc + b? In that case:

b in y = mx + b format is the y-intercept, as this kind of equation is called slope-intercept form.
