2 answers:
Answer:
20π
Step-by-step explanation:
C=2πr=2*10π=20π
Circumference is 62.8
To find the circumference, the formula is 2πr
The radius is half so we must multiply by 2 which is 20.
And finally, you multiply by π (3.14) and you will get 62.8 cm.
In conclusion, the answer is 62.8 cm.

Answer:
Step-by-step explanation:
(4b^2+3)(4b^2-3)
since it is the expanded form of formula a^2-b^2=(a+b)(a-b) we can write,
=(4b^2)^2-(3)^3
=16b^4-9
To find out how many brothers they have, they need to multiply 4×1= 4
So there are 4 brothers.
