Answer:
Step-by-step explanation:
- Diagonals of a rhombus are perpendicular.
- Sides are of equal length.
<u>Use Pythagorean to work out the side length.</u>
- a² = (d₁/2)² + (d₂/2)²
- a² = (24/2)² + (45/2)² = 650.25
- a = √650.25
- a = 25.5 cm
<u>The perimeter is:</u>
- P = 4a
- P = 4*25.5 = 102 cm
Answer:
a = 6
b = 48
Step-by-step explanation:
3*2^1 = 6
3*2^4 = 48
Answer:
yep
Step-by-step explanation:
when you divide a fraction u can use the KCF method which is basically:
(keep) the first fraction the same
(change) the division sign in the middle to a multiplication sign
(flip) the second fraction
basically because you have to flip the 1/4 when you divide it, it'll be the same as a 4/1 anyways
Firstly , we will locate centres and radius in the figures
(a)
We can see that
centre=(h,k)=(0,0)
radius=r=5
now, we can use standard equation of circle
we can plug values
we get
(b)
We can see that
centre=(h,k)=(5,4)
radius=r=3
now, we can use standard equation of circle
we can plug values
we get
(c)
We can see that
centre=(h,k)=(4,3)
radius=r=5
now, we can use standard equation of circle
we can plug values
we get
