Answer:
B. (x+1)^2 + (y-7)^2=196
Step-by-step explanation:
The equation is (x-h)^2 + (y-k)^2=r^2
h=-1,k=7 and r=14
(x-(-1))^2 + (y-7)^2= 14^2
(x+1)^2 + (y-7)^2 = 196
Answer:
180 sq. in.
Step-by-step explanation:
The formula for the volume of a circular cone is V = (πr^2h)/3
So, 900 = (15πr^2)/3
2700 = 15πr^2
180 = πr^2 = area of the circular base
Answer: 90 textbooks
Step-by-step explanation:
everytime you multiply the number of students you multiply the books by the same number. to find how many times 72 was multiplied you divide it by 12.
72 ÷ 12 = 6
then multiply the original number of books (15) by 6.
15 * 6 = 90
so for every 72 students the school orders 90 textbooks
Two-hundred thirty six thousandths
Hope this helps!
