Answer:
23.7°
9.1~ft
Step-by-step explanation:
Formula for the area of a sector of central angle n (in degrees) and radius r:

We have:
A = 100 ft^2
r = 22 ft
We need to find:
r


The central angle measures 23.7°.
Formula for the length of an arcs of a circle with central angle n (in degrees) and radius r:

We have:
n = 23.7°
r = 22 ft
We need to find:
s


Since he completes 10 minutes each day for five days, he completes 50 minutes.
The percentage of his total requirement would be 50/100 = 0.5 = 50%.
Answer:
CA = 5
Step-by-step explanation:
Since the sides are 3 and 4, we recognize this as a 3:4:5 right triangle, with CA = 5. Using the Pythagorean theorem confirms this:
CA² = AB² +BC²
CA² = 3² +4² = 9 +16 = 25
CA = √25
CA = 5
