Answer:

For the first one about Jack the answer to A is 14, 21, 30 and for b the answer is 22. Now for Maria the answer for A is 24 , 40 , 80 and for b it's 8

Step-by-step explanation:

All you had to do for Jack was just add 10 to each number that's for A Now for B you just had to minus ( - ) 10 from 32 which equals 22. For Maria You needed to times ( × ) every number from 4 .

A new restaurant is attracting customers with searchlights has a radius of 2 feet. What is the searchlights circumference?

Assoli18 [71]

Answer:

12.56 feet

Step-by-step explanation:

The perimeter of a shape is the sum of all its side.

Since circle doesn't have "sides", the perimeter is the length of the whole circle. This has the name "circumference".

The circumference of a circle has the formula:

$C=2\pi r$

Where

C is the circumference (perimeter of a circle)

r is the radius

Given,

r = 2 feet

We substitute and find the circumference, using 3.14 as $\pi$ ,

$C=2\pi r\\C=2(3.14) (2)\\C=12.56$

Hence, the circumference is 12.56 feet
