The measure of angle pqr is 75°. the length of radius qr is 8 inches. what is the approximate area of sector pqr? use 3.14 for pi .

  about 41.9 square inches

Step-by-step explanation:

The area of a sector of radius r and central angle α is given by ...

  A = (1/2)r^2·α

where α is in radians.

The angle 75° is equivalent to 75°·(π/180°) = 5π/12 radians, so the area is ...

  A = (1/2)(8 in)^2·(5/12)·3.14 = (40/3)·3.14 in^2 = 41.86_6 in^2 ≈ 41.9 in^2

Comment on the precision of the answer

The use of a 3-significant-digit value for pi means that the answer must be rounded to 3 significant digits. If the 8-inch value for radius is really only accurate to ±1/2 inch, then the answer must be rounded to 1 significant digit: 40 in^2.

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
