Answer:

answer d and e

Step-by-step explanation:

First, you need to figure out the radius of B.

As radius of A is 6 in, 20% of 6in would be 1.2in. So total radius of B = 6+1.2 = 7.2

Now you get the radius of B, calculate th area of B using the formula πr^2.

= π(7.2)^2 = 162.86 = area of B

Now, all answers except D and E is smaller than B. So, the answer would be D and E.

Answer:

  A, E

Step-by-step explanation:

The radius of Circle B is 20% greater than 6 inches, so is ...

  r = (6 in)(1 +20%) = 1.2×6 in = 7.2 in

The area of Circle B is ...

  A = πr²

  A = π(7.2 in)² ≈ 162.86 in²

The offered answer choices (and the area of Circle B) in order from least to greatest are ...

  [B]51.84, [C]113.04, [F]148.49, [D]162.78,

  (circle B)162.86,

  [A}189.31, [E]203.15

Choices A and E are greater than Circle B's area.

A student is evaluating the expression below for n=3.7.12.8+6(n-0.5) in what order should the student do the steps?
jeka94

Answer:

32

Step-by-step explanation:

The given expression is :

12.8+6(n-0.5)

We need to evaluate the expression for n = 3.7

Put n = 3.7 in the above expression.

12.8+6(3.7-0.5)

= 12.8+6(3.2)

= 12.8 + 19.2

= 32

So, the value of the given expression is equal to 32.
