area of the whole circle = r^2 times pi
radius is 10 units
thus, the whole circle's area is 100pi square units.

...and this shape is exactly one quarter, one-fourth, of the whole circle. Why? because of the shape's right angle and radius. (when you multiply 90 times 4, it will equal 360 degrees, which is the angle of a whole circle.)

so 100pi divided by 4 equals 25pi square units of the shape.

ANSWER:

25 pi square units

(or in decimals: multiply 25 by 3.14 which would be 78.5 square units)

Jon has to pay $7.00 admission for the skating rink in $1.50 per hour to rent rollerblades. How many hours can he skate for $19?

eduard

Answer: 8 hours

Step-by-step explanation:

Given information

Admission fee = $7.00

Hour rent fee = $1.50

Number of hours = h

Total fee = $19

Set equation according to the given information

Total fee = admission fee + (hours) × (hour rend fee)

Substitute values into the equation

19 = 7 + 1.5h

Subtract 7 on both sides

19 - 7 = 7 + 1.5h - 7

12 = 1.5h

Divide 1.5 on both sides

12 / 1.5 = 1.5h / 1.5

$\boxed{h=8}$

Hope this helps!! :)
