Hello!
What is the exact circumference of the circle?
A.
10π feet
B.
20π feet
C.
40π feet
D.
60π feet
Solving: Using the data (Circle with center A and diameter of 20 feet labeled).
diameter = 2*radius
Formula: (Circle length)
Now, replace in the circumference length formula:
Answer:
B. 20π feet

A = 3.125
Sorry I only know A.
You would divide 500 by 160.
Answer:4 pens for 56
Step-by-step explanation:
Add all shapes area together to know the figures complete area
triangles area 1 & 2 : 6×8 /2 -> 48/2 = 24
rectangle 1 : 6×12 -> 72
rectangle 2 : 8×12 -> 96
rectangle 3 : 10×12 -> 120
24+72+96+120
96+96+120
192+120
312cm
Answer:
B
Step-by-step explanation:
Given
x² - 18x + --- = 4 + ----
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 9)x + 81 = 4 + 81
(x - 9)² = 85 ( take the square root of both sides )
x - 9 = ± ( add 9 to both sides )
x = 9 ± ← exact solutions
