Answer:
Step-by-step explanation:
angle subtended at center in 15 minutes=360÷60×15=90°=π/4
distance traveled by minute hand=2πr/4=πr/2=6π/2=3π inches≈9.42 inches
distance travelled by minute hand in 25 minutes=2πr×25/60=50πr/60=5/6πr
≈5/6 π×6=5π inches ≈15.71 inches
Ellipse area = PI * a * b
ellipse area = 3.14 * 8 * 7
ellipse area = 175.84
2.75a=19.25
19.25/2.75
a = 7
- So basically what I did was convert 2 3/4 and 19 1/4 into decimals. From there I divided 2 3/4 (2.75) by 19 1/4 (19.25) and I got 28.
- The numbers in parenthesis is the numbers in decimals.
- I hope that helps!!!!!
