Area of the square:

7 * 7 = 49

Area of the circle:

A = πr²

7 / 2 = 3.5 (diameter)

A = π(3.5)²

A = 12.25π

A = 38.465

Subtract both area.

49 - 38.465 = 10.535 or 10.54cm²

Best of Luck!

Answer:

Step-by-step explanation:

area of square = 7 x 7 = 49

area of circle = pi x diameter^2/4 = 3.14 x 7^2/4 = 38.46

shaded area = square - circle

= 49 - 38.46

= 10.54

Find the Quotient and Remainder. 5x^3 - 6x^2 + x + 7 divided by x^2

12345 [234]

Step-by-step explanation:

Solution

According to remainder theorem, when f(x) is divided by (x+2), Remainder =f(−2)

f(x)=5x3+2x2−6x+12

f(−2)=5(−2)3+2(−2)2−6(−2)+12

=5×−8+2×4+12+12

=−40+32=−8

∴ Remainder=−8

You wish to borrow $8000 for debt consolidation. The bank's interest rate for a personal loan is 7.2%. What is your monthly paym

Lisa [10]

<h3>The monthly payment is $242.44 for loan to paid off in 3 years.</h3>

Step-by-step explanation:

The amount borrowed = Principal = $8000

The rate of interest = 7.2%

Time (T) = 3 years

Now, Simple Interest = $\frac{P\times R \times T}{100}$

$\implies SI = \frac{8000 \times 7.2 \times 3}{100} = 1,728$

So, the total interest = $1728

Now, Amount to be paid = Principal + Interest

⇒ A = $8000 + $1728 = $8728

Also, 1 year = 12 months

⇒ 3 years = 3 x 12 months = 36 months

So, total amount to be paid in 36 months is $8728.

⇒The amount to be paid in 1 month is $(\frac{8728}{36} ) = 242.44$

Hence, the monthly payment is $242.44 if loan is to paid off in 3 years.
