Answer:
The radius of the circle is 
Step-by-step explanation:
we know that
The circumference of a circle is equal to

In this problem we have


substitute and solve for r


Answer:
the rule for rotating 90 degrees clockwise is (x,y) to (y,-x). (3,2) will turn into (2,-3)
Step-by-step explanation:
Remember that the cone volume formula is
, with r = radius and h = height. Using our information, we can form our equation as such:
(I'll be keeping the answer in pi form.)
Firstly, solve the exponents:
Next, multiply 4 and 19/3 together and your answer should be (rounded to the hundreths): V = 25.33π un^3
The answer should be C but I’m not for sure ask your teacher sorry!!
