Answer:
40πcm
Step-by-step explanation:
circ = 2πr
if d = 40cm
r = 20cm
∴ c = 2×π×20
= 40πcm
= 125.66cm
Answer:
Step-by-step explanation:
The right hand one on the left side is
250 + 360 = 610
The next one is going to be
250 + 360 + 360
250 + 720
970
This problem is very lucky. You just add 360 for the first angle and another 360 for the second one.
Can you just add 360 to 610 Yes you can but I don't think it's as easy to see. 360 + 610 = 970
You are the boss. Take your pick.

Answer:
Step-by-step explanation:
The given expression is
(4×10^8)(4×10^-7)/(4×10^8)
Considering the property of exponents which is expressed as
y^a × y^b = y^(a + b)
Applying the above rule to the denominator of the given expression, it becomes
4×10^8 × 4×10^-7 = 16 × 10^(8 + - 7)
= 16 × 10^(8 - 7)
= 16 × 10 = 160
The expression becomes
16 × 10/(4×10^8)
We would apply the property of exponents which is expressed as
y^a ÷ y^b = y^(a - b)
It becomes
16/4 × 10^(1 - 8)
= 4 × 10^-7
