Answer:
210.25 or 210.3495409 depending on how your teacher does it
Step-by-step explanation:
Looking for circumference of the circle when it asks for perimeter
Formula for Circumference C = π x r <em>3 (cubed)</em>
The diameter is 10 so you take half of ten or 10 ÷ 2 = 5
5 x 5 x 5 = 125 (r squared equation)
125 x π = 392.6990817
Some classes ans stuff use 3.14 for pi so i'll show it that way too
125 x 3.14 = 392.5
(equation with π)
392.6990817 ÷ 2 = 196.3495409
196.3495409 + 14 = 210.3495409
(equation with 3.14)
392.5 ÷ 2 = 196.25
14 + 196.25 = 210.25
Answer: See explanation
Step-by-step explanation:
Total number of children = 369
Percentage of children on museum trip = 20%
Number of children on museum trip = 20/100 × 369
= 1/5 × 369
= 73.8 = 74 approximately
Number of children in school = 369 - 73.8 = 295.2 = 295 approximately
To find reference angle you need to subtract all 360⁰ that given angle has.
360*2=720
791-720 = 71⁰
<span> The reference angle for 791⁰ is 71⁰.</span>
