Answer: The artist used 8.6 inches more of silver wire
Step-by-step explanation:
Perimeter of the square
P = 4*a
P = 4*a = 40 in
a = 10 in
Each side of the square has a length of 10 in
The diameter of the circle is equal to the length of the side of the square
Diameter = 10 in
Perimeter of the circle
P_c = 2*π*radius = π*diameter
P_c = (3.14)*10 in = 31.4 in
Inches of silver wire (square) = 40 in
Inches of copper wire (circle) = 31.4 in
40- 31.4 in = 8.6 in
Find how many miles they traveled per minute.
90/75 = 1.2 miles per minute
If two hours = 120 minutes, calculate how many miles they will travel
120 x 1.2 = 144 miles. The answer is A.
C = pi x d
So the border is about 3.1 x 20 = 62 inches
Answer: 8
Step-by-step explanation:
20*.4=8
Answer:
Hello,
-4 x + 11 y = 15 ⇔ -4 (2 y) + 11 y = 15 ⇔ 3 y = 15 ⇔ y = 5
x = 2 y = 10
