Answer:
3.71 cm
Step-by-step explanation:
Hi there!
Area of a circle equation:
where r is the radius
Plug in the area 43.25 cm²

Divide both sides by π to isolate r²

Take the square root of both sides to isolate r

Therefore, the length of the radius rounded to 2 decimal points is 3.71 cm.
I hope this helps!
The distance between city C and city D is 450 miles.
<u>Solution:</u>
Given, The distance between City A and City B is 250 miles.
A length of 2.3 feet represents this distance on a certain wall map.
City C and City D are 4.14 feet apart on this map.
We have to find what is the actual distance between City C and City D?
Now, distance between a and b is 250 miles ⇒ 2.3 feet on map
Then, distance between c and d be n miles ⇒ 4.14 feet on map.
Now, by chris cross method.
250 x 4.14 = 2.3 x n miles.
2.3n = 1035
n = 450
Hence, the distance between city C and city D is 450 miles.
The mass should be 75.71 grams
To find density is D = M / V
So you would have to multiply the volume by the density
C. trapezoid
a trapezoid's legs are congruent, while the bases are symmetrical
a square is the answer you would want, because it is always true, while a trapezoid is only "sometimes" true
