Answer:

Valek did not correctly divide 1,536 by 20 going from step 3 to step 4. Valek did not find the correct product of 32 and 48 going from step 2 to step 3. Valek should have written the proportion in step 1 as 32/20 = PR/48.

Cake has a circumference of 20.41 inches what is the area of the cake used 3.14 approximate round to the nearest 10th
hichkok12 [17]

Answer:

33.2 inches²

Step-by-step explanation:

Steps to derive the answer

  1. we are going to first determine the radius from the circumference
  2. we would calculate the area

Circumference of a circle = 2nr

n = 3.14

r = radius

20.41 = 2x 3.14 x r

Divide both sides by (2 x 3.14)

r = 3.25 inches

Area of a circle = nr²

3.14 x  3.25² = 33.2 inches²

Step2247 [10]

Answer:

The slopes of line m and p will be the same: 1/25 (I think thats what that says)

Step-by-step explanation:

when two lines are parallel it means they will never touch, and so they must have the same slope. If their slopes were different (even by 1 decimal), they would touch and so would no longer be parallel.
