Answer: 39 untits 2
Step-by-step explanation:
Hi, to answer this question, first we have to calculate the perimeter (sum of sides) of the triangle:
Perimeter: 7+6+9.22 = 22.22 units
Then we have to apply the circumference (C) formula:
C = π x diameter
Since C = perimeter of the triangle:
22.22 = 3.14 d
22.22 /3.14 =d
7.08 = d
Finally, we apply the next formula:
Area of a circle = π (d/2)^2
Replacing:
A = 3.14 (7.08/2)^2 = 39.30 units2 = 39 units 2
Based on the theory, the distance from the starting point to the return point = Arc length = 109.9 feet.
<h3>What is the Length of an Arc?</h3>
Arc length = ∅/360 × 2πr
Since the sector formed is a quarter circle, then ∅ = 90°.
Raidus (r) = 70 ft
Distance from the starting point to the return point = arc length.
Arc length = ∅/360 × 2πr = 90/360 × 2π(70)
Arc length = 109.9 feet
Therefore, based on the theory, the distance from the starting point to the return point = Arc length = 109.9 feet.

Answer:
yesnt
Step-by-step explanation:
Answer:
110 words in 5 min, 220 words in 10 min
Step-by-step explanation:
y = mx (there is no intercept because you can't type anything in 0 minutes)
66 = 3m
m = 22
y = 22x
5 minutes:
y = 22(5) = 110 words
10 minutes:
y = 22(10) = 220 words
