Question 6 options: What is the approximate area of a circle with a diameter of 56 cm? Use your calculator button for π. Round y

Andrew [12]

The area of circle is 2463.0086 cm².

Step-by-step explanation:

Given,

Diameter of circle = 56 cm

Radius of circle = $\frac{Diameter}{2}$

Radius of circle = $\frac{56}{2}=28\ cm$

We know that;

Area of circle = $\pi r^2$

Area of circle = $\pi *(28)^2$

Area of circle = π * 784

Area of circle = 2463.00864041 cm²

Rounding off to four decimal places

Area of circle = 2463.0086 cm²

The area of circle is 2463.0086 cm².

2) Lisa is ordering sand from the Internet, On one site she found sand on sale for

Anastasy [175]

For this case we must find the unit cost (dollars per pound) of each site and then compare.

We take into account that:

1kg equals 2.205 pounds

So, we have:

Site 1:

$C = 2.25 \frac {dollars} {pound}$

Site 2:

$5kg = 5 (2.205\ pounds) = 11.025 pounds$

So, the unit cost is:

$C = \frac {14} {11.025} \frac {dollars} {pound} = 1.27 \frac {dollars} {pound}$

Thus, the best deal is on site 2.

ANswer:

The best deal is on site 2.

Edg vector operations, any help appreciated!

viktelen [127]

$\quad \huge \quad \quad \boxed{ \tt \:Answer }$

$\qquad \tt \rightarrow \: Add \:\: -6 \hat i - 6\hat j \:\:with \:\; Vector \:\; c$

____________________________________

$\large \tt Solution \: :$

Vector d can be represented as :

$\qquad \tt \rightarrow \: - 2 \hat i - 2 \hat j$

Vector c can be represented as :

$\qquad \tt \rightarrow \: 4 \hat i + 4\hat j$

we have to create vector d from vector c

So, let's assume a vector x, such that sum of vector x and vector c equals to vector d

$\qquad \tt \rightarrow \: x + ( 4 \hat i + 4 \hat j) = - 2 \hat i - 2 \hat j$

$\qquad \tt \rightarrow \: x = - ( 4 \hat i + 4 \hat j) - 2 \hat i - 2 \hat j$

$\qquad \tt \rightarrow \: x = (- 4 \hat i - 2 \hat i) + ( - 4 \hat j - 2 \hat j)$

$\qquad \tt \rightarrow \: x = - 6 \hat i -6 \hat j$

Henceforth, in order to get vector d, we need to add (-6i - 6j) in vector c
