Answer:

♕ \large{ \tt{EXPLANATION}} :

  • We are provided the diameter of a circle i.e 7 cm & we're asked to find out the circumference of a circle.

  • We know , the value of pi is always 3.14 or 22/7. Here , we're gonna put the value of pi as 22/7.

\large{ \tt{❊ \: SOLUTION}} :

\boxed{ \tt{❃ \: Circumference \: Of \: Circle =  \pi \: d}}

Plug the values & then multiply :

\large \tt \: ↬C =  \frac{22}{7}  \times 7

\large \tt ↬ C = \frac{22}{ \cancel{7}}  \times  \cancel{7}

\large{  \boxed{  \tt{↬C = 22 \: cm}}}

\boxed{ \boxed {\large {\tt{⟿ \: OUR \: FINAL \: ANSWER :  \boxed{ \underline{ \tt{22 \: cm}}}}}}}

✺ \large{ \tt{STUDY\: TIP}} :

Let f(x) = (5)^x+1 .Evaluate f (-3) without using a calculator
rewona [7]

Answer:

f\left(-3\right)=\frac{126}{125}

Step-by-step explanation:

Given

f\left(x\right)\:=\:\left(5\right)^x+1

Putting x = -3 to find f(-3)

f\left(-3\right)\:=\:\left(5\right)^{\left(-3\right)}+1

as

5^{-3}=\frac{1}{125}       ∵  \mathrm{Apply\:exponent\:rule}:\quad \:a^{-b}=\frac{1}{a^b}

so

f\left(-3\right)=\frac{1}{125}+1

\mathrm{Convert\:element\:to\:fraction}:\quad \:1=\frac{1\cdot \:125}{125}

f\left(-3\right)=\frac{1\cdot \:\:125}{125}+\frac{1}{125}

\mathrm{Since\:the\:denominators\:are\:equal,\:combine\:the\:fractions}:\quad \frac{a}{c}\pm \frac{b}{c}=\frac{a\pm \:b}{c}

f\left(-3\right)=\frac{1\cdot \:\:125+1}{125}

f\left(-3\right)=\frac{126}{125}      ∵ 1\cdot \:125+1=126

Thus,

f\left(-3\right)=\frac{126}{125}

Which techniques can be used to evaluate the expression 12.75/<br><br> 1.5
sergeinik [125]

Answer:

8.5

Step-by-step explanation:

Given the expression 12.75/1.5. The technique in solving the division expression is as shown

First we can write the decimals as fraction as shown;

12.75 = 1275/100

1.5 = 15/10

12.75/1.5 = (1275/100)÷(15/10)

12.75/1.5 = 1275/100×10/15

12.75/1.5 = 1275/10 × 1/15

12.75/1.5 = 1275/150

12.75/1.5 = 8.5

Hence the result of the division is 8.5
