Answer:
10/21 units²
Step-by-step explanation:
2/3 x 5/7 = 10/21 units²

The equation of a circle is represented as :

where,
- "h" represents x - coordinate of the center of circle
- "k" represents y - coordinate of the center of circle
- " r " represents Radius of the given circle
So, from above equation we get:
Therefore, Radius of the given circle measures 6 units.

Answer:
73 degrees.
Step-by-step explanation:
So, let's see the information provided in the question.
At 8 AM, the thermometer was reading -5 degrees.
At 12:30 PM, the temperature has increased by 11 degrees, so it's now +6 degrees outside.
Inside Susan's house, the temperature is 7 degrees more than 11 times the outside temperature, at 12:30 PM.
So, we know the outside temperature at 12:30 PM is +6 degrees.
11 times 6 = 66 degrees.
Then we add the additional 7 degrees, to get a total of 73 degrees.
