Answer:
rectangle, square, circle
Step-by-step explanation:
Rectangle: length: 10 feet, Width: 50/10=5 feet
Square: length: 50/4=12.5 feet
Circle: 2pi(r)=50, radius=25/pi
A = ab ( the area of rectangle )
a b = 192
a b r² = 363
192 r² = 363
r = √363 / 192 = √121/64
r = 11/8
The similarity ratio of the two rectangles is 11/8.
Answer:
0.2
Step-by-step explanation:
14/10÷x=7
14/10=7x
1.4±7=x
x=0.2
So the formula for the circumference of a circle is π x diameter
Since we know the the circumference already, we just divide that by π:
12π / π = 12
Now we halve the diameter to get the radius:
12 / 2 = 6
The area of a circle is π x radius²
So the area is:
·π x 6² = 36π· (or 113 not in terms of π)
Answer:
You can decide where to put the first digit because you know 153 doesn't fit into 6 or 61. But you know it can fit into 613. You put it there.
