Answer: 78
Step-by-step explanation:
The rest of the answers are too small to be the length.
Do you need an explanation of the work shown? The distance can be found by multiplying the rate by the time. as long as you know two of three parts, you can find the missing value. There is no problem shown in the picture?
Answer:
To find the sum of interior angles in a polygon, we can use the formula:
where n is the number of sides.
Since this is pentagon (5 sides), then 
The missing angle would then be
Since angles on a straight line add up to 180, then
Hey there! :)
The formula for finding area of circles is: π · r²
<em>Remember that radius is half the diameter. To find radius when the diameter is given, divide by 2</em>
d = 26
26 ÷ 2 = 13
_____________________________________________________________
π · r²
r = 13
13² = 13 × 13 = 169
169 × 3.14 = 530.66 = 530.7
The area of the swimming pool is 530.7 ft²
Hope this helps :)
