A circle with center at (-2,2) passes through (7,2). Find the circumference and area of the circle in terms of p.
1 answer:
Answer:
18pi units is the circumference
81pi units² is the area
Step-by-step explanation:
Radius² = (-2-7)² + (2-2)² = 9²
Radius = 9
Circumference = 2pi×r
= 18pi
Area = pi × r²
= 81pi

Legnth are x and y
x+y=100
one is 16 more than other
x is 16 more than y
x=16+y
x=16+y therefor we can put 16+y for x
(16+y)+y=100
16+y+y=100
16+2y=100
minus 16 both sides
2y=84
divide by 2
y=42
sub back
x=16+y
x=16+42
x=58
the legnsh are
42 cm and 58cm
4.4 is the correct answer, hope this helps!

Answer:
x = -4 and x = -2
Step-by-step explanation:
Answer:
<em>(n - 5)(n + 5) </em>
Step-by-step explanation:
a² - b² = (a - b)(a + b)
n² - 25 = n² - 5² = <em>(n - 5)(n + 5)</em>
