A plate has a diameter of 14 inches . what is the approximate circumference of the plate?

1 answer:

3 0

Circumference formula is 2(pi)r^2
so you need to find the radius(diameter/2) r=7
then multiply 7 x 3.14= 21.98
then multiply by 2 21.98 x 2= 43.96
answer is B 43.96

What is the area of the polygon given below?

ehidna [41]

Hello!

First of all, let's find the area of the upper rectangle. We have side lengths 5 and 6, so its area is 30.

Now to find the bottom. If we add our ten, and the five on top, we get a length of 15. We multiply this by 6, giving us 90.

Now we add.

90+30=120

Therefore, our answer is A) 120 square units.

I hope this helps!

Two parallel lines are crossed by a transversal. Determine the degree measure of each angle, then identify each angle's relation

denis-greek [22]

When Two parallel lines are crossed by a transversal

m∠1 = 124 ° , Relationship : Linear pair of angles

m∠2 = 56 ° , Relationship : Alternate interior angles

m∠3 = 56 ° , Relationship : vertical opposite angles

Given :

Two parallel lines are crossed by a transversal

In the diagram , it is given an angle that measures 56 degrees

m<1 and 56 are linear pair . Sum of linear pair of angles is equal to 180

$m$

∠2 and 56 are inside the parallel lines and they are opposite

<2 and 56 are alternate interior angle . Alternate interior angle are equal

$m$

<3 and 56 are opposite to each other. They are vertical opposite angles .

Vertical opposite angles are equal .

$m$

6. We want to build the smallest cube possible using bricks with dimensions 8 cm - 12 cm 20 cm. How many bricks do we need?

Georgia [21]

Answer:

1200

Step-by-step explanation:

We’ll need a number that is evenly dividable by all three values: 8,12 & 15. We can develop the generic common multiple by multiplying all three numbers and get 1440. But is that the smallest common multiple? The quick and dirty way to factor the number is to divide it by it’s various elements and see what works. In this case 1440/12=120 which is the smallest common multiple of the three numbers. The smallest length is therefore 120.

In order to find how many bricks just divide (120x120x120)/(8x12x15)=1200 bricks
