The picture in the attached figure

we know that
area of the circle=pi*r²

if 45° has an area-------> 18*pi units²
360° (full circle)----------> x
x=360*18*pi/45-----> x=144*pi units²

area of circle=pi*r²
144*pi=pi*r²------> r²=144--------> r=√144-----> r=12 units

I need help with 64 and 65
Tcecarenko [31]

Answer:

65 would be C

Step-by-step explanation:

it wants you to find out how much was spent after 11 visits. 10 dollars is used each time so 11 times 10 is 110. 306 minus 110 equals 196. you would choose C instead of B because the 10 is the one being multiplied, not 306.

306-10x; $196

Xavier works at Art Van Furniture. He is paid on commission. He receives 12% of
Scilla [17]

Based on the commission that Xavier receives from Art Van Furniture, the total value of the furniture sold is $5,500.

<h3>How much furniture did Xavier sell?</h3>

The commission that Xavier earns on his first $1,000 should be removed to be:

= 930 - (12% x 1,000)

= $810

This value of $810 is 18% of the balance of Xavier's sales:

= 810 / 18%
= $4,500

Added to the first $1,000, Xavier's total sales are:

= 4,500 + 1,000

= $5,500
