Answer: 21 mins to peel the balanced potatoes
Step-by-step explanation:
Answer:
1/2 pi
Step by step explanation:
Find the circumference
2πr = 2xπx2 = 4π
Find the angle of JHI
Since 1/2π is 1/8 of 4π,
Angle JHI should also be 1/8 of 360 = 45 degrees
To find area, 45/360 x π X 2^2
= 1/8 x 4π
= 1/2 π
0.0009208 you can round it to 0.0009 if you want.
Try this option:
According to property such triangle
1. area=0.5*a*b, where a and b - the sides of angle 90°.
Using this equation: 180=0.5*40*b, ⇒ b=9.
2. c²=a²+b², ⇒c=√(9²+40²)=41 - the third side of the triangle;
3. Perimeter=a+b+c=9+40+41=90 cm.
answer: 90 cm.
