Answer:what the answer choice or is the any?
Step-by-step explanation:
Let's model the problem like a circle.
The circumference of a circle is given by:
Where,
r: radius of the circle.
Clearing the radius we have:
Then, replacing values we have:
Answer:
The best approximation for the radius of the tin is:
It would be first 0.86 then it would be 8/9 and the le last one would be 0.9
Answer:
199 if it's 7b^3 + 10
9271 if it's (7b)^3 + 10
Step-by-step explanation:
You just substitute the 3 in for d. If your expression was 7b^3 + 10, then only b is being raised to 3.
So 3^3 is 27, 27*7 is 189, 189+10 is 199.
If the expression was (7b)^3 + 10, then first you multiply 7 and 3 to get 21. Then you raise 21 to the power of 3, which is 9261. Then you add 10, which is 9271.
