The chemistry teacher decides to use chalk paint to cover a circular portion of a wall in the science lab. If the greatest distance across the circle is is 3 feet, approximately how many square feet will the chalk paint cover?
A) 5 ft²
B) 7 ft2
C) 9 ft2
D) 11 ft2

Determine the number of outcomes in the event. decide whether the event is a simple event or not. upper a computer is used to select randomly a number between 1 and 9 comma inclusive. event upper b is selecting a number greater than 4. event upper b has nothing outcome(s). is the event a simple event? (yes or no) because event upper b has (fewer than, exactly, more than) one outcome.

Evaluate 3(a + b + c)squared for a = 2, b = 3, and c = 4. a. 54 b. 243 c.729 add solution .

The sum of the squares of two numbers is 8 . the product of the two numbers is 4. find the numbers.
