What is the area of the shaded region?

Answer:

A=5.29\pi

Step-by-step explanation:

<u>Formula for circumference of a circle is</u>:

Circumference = 2\pi r


<em>Given circumference of the ring is 4.6\pi</em>

<em>Now solving for the radius gives us:</em>

2\pi r=4.6\pi\\r=\frac{4.6\pi}{2\pi}\\r=\frac{4.6}{2}=2.3


We know that area of a circle is \pi  r^2, substituting the value of r we found, we get the area as:

area (A) = \pi r^2\\\pi (2.3)^2\\\pi (5.29)\\=5.29\pi


Hence the Area (A), in terms of \pi is 5.29\pi

find the amount and the compound interest on rupees 12000 at 6% p.a. compounded half yearly for 3/2 years ​
stiv31 [10]

Answer:

A= ₹3,112.72

CI = ₹1,112.72

Step-by-step explanation:

Here P = ₹ 12000

Since, interest is compounded half yearly.

Therefore, R = 6/2 = 3%

n = 3/2* 2 = 3 half years

\because A= P\bigg(1+\frac{R}{100}\bigg)^n

\therefore A= 12000\times \bigg(1+\frac{3}{100}\bigg)^3

\therefore A= 12000\times \bigg(\frac{100+3}{100}\bigg)^3

\therefore A= 12000\times \bigg(\frac{103}{100}\bigg)^3

\therefore A= 12000\times \bigg(1.03\bigg)^3

\therefore A= 12000\times 1.092727

\therefore A= 13,112.724

\therefore A=Rs. \:13,112.72

CI = A - P

CI = 13,112.72 - 12000

CI = ₹1,112.72

A line passes through the point (8,7) and has a slope of negative 3/4 Write an equation in slope-intercept form for this line.
Anton [14]

Answer: Y= -3/4x+13


Step-by-step explanation:

A line passes through the point (8,7) and has a slope of negative 3/4 Write an equation in slope-intercept form for this line.

This is what i get

Slope of a line Y= mx+b

Y= 7

X= 8

M= -3/4


7= -3/4(8)+b

7= -6+b

7+6=b

13=b


Y= -3/4x+13
