The circumference of the circle is 37.68 ft
Step-by-step explanation:
Given,
The area of the circle is 113.1 sq ft
To find the circumference of the circle we need to find the radius of the circle first
Formula
The area of circle with radius r is = π sq unit
The circumference of circle with radius r is = 2πr unit
Let us take the radius of the circle is r ft
According to the problem,
π
or,
or,
or, r =
or, r = 6
Now,
The circumference of the circle is 2×3.14×6 ft = 37.68 ft
Answer:
d = 6.1m
n = 7km
Step-by-step explanation:
To find the variables, use tan
⇒ tan =
finding d:
⇒tan 63 =
tan of 63 is 1.963
⇒ 1.963 =
multiply 3.1 on both sides
⇒ 1.963 x 3.1 = x 3.1
⇒ 6.0853 = d
round to the nearest tenth:
⇒ 6.0853 = 6.1
finding n:
⇒ tan 45 =
tan of 45 is 1
⇒ 1 =
multiply 7 on both sides:
⇒ 1 x 7 = x 7
7 = n
