Answer:
10 pi
Step-by-step explanation:
Since this is a cylinder, we know that the long side of the rectange will go all around the circle. This length is known as the circumference, and the formula of a circle's circumference is pi * diameter. We know the circle's radius is 5, and double that would be the diameter, 10. Therefore, pi * 10 is 10pi, which is ur answer
Whole number because it’s not the others
Answer:
Step-by-step explanation:
Question 3
5 (k + 4) - 2k
Use distributive property of multiplication.
5k + 20 -2k
Combine like terms to get your answer.
3k +20
Question 4
2 (3 + d - 1)
Simplify the expression in the parenthesis.
2 (2 + d)
Use distributive property of multiplication.
4 + 2d
If you wanted it to be accepted at higher levels, switch the terms around.
2d + 4
It becomes 7/40. To get it, you have to put 1/8 times 5/7. Then, flip the second fraction, (5/7), so that it becomes 7/5. Multiply 1/8 and 7/5, to get 7/40. You call this "reciprocal".
