Find the surface area and show work

Law Incorporation [45]

Answer: $1,270in^2$

Step-by-step explanation:

The surface area of a rectangle can be calculated with:

$Area_{rectangle}=lenght*width$

The surface area of a trapezoid can be calculated with:

$Area_{trapezoid}=\frac{height}{2}(Larger\ base+Smaller\ base)$

Calculate the area of the base, wich is a rectangle:

$A_{1}=(34in)(15in)=510in^2$

There are two equal rectangles, therefore, multiply the area of any of them by 2:

$A_{2}=2(15in)(13in)=390in^2$

Calculate the area of the other rectangle:

$A_{3}=(15in)(10in)=150in^2$

There are two equal trapezoids, therefore, multiply the area of any of them by 2:

$A_4=\frac{2(5in)}{2}(34in+10in)=220in^2$

Therefore, the surface area will be the sum of all the areas calculated:

$SA=A_1+A_2+A_3+A_4\\\\SA=510in^2+390in^2+150in^2+220in^2\\\\SA=1,270in^2$

Ed needed to extend the string on his kite. The current string was eight and three fourths feet. He cut a piece of string that m

Pani-rosa [81]

The new length of the string is (13 + 1/4) feet, then the correct option is the last one (counting from the top)

<h3> What is the new length of the string?</h3>

We know that the current string was (8 + 3/4) feet in length. Then they add another piece that measures 4.5 feet.

The new length of the string is given by the addition of the above two lengths, we will get:

L = (8 + 3/4) feet + 4.5 feet

We can rewrite the second length as a mixed number:

4.5 = 4 + 1/2 = 4 + 2/4

Replacing that we get:

L = (8 + 3/4) ft + 4.5 ft

= (8 + 3/4) ft + (4 + 2/4) ft

= (8 + 4) ft + (3/4 + 2/4) ft

= 12ft + 5/4ft = 12ft + (4/4 + 1/4)ft = (13 + 1/4)ft

The new length of the string is (13 + 1/4) feet, then the correct option is the last one (counting from the top).

Hurry! Answer ASAP! 20 points

zzz [600]

Answer:

30 inches

Step-by-step explanation:

The circumference of a circle can be found by using 2 $\pi$ r, or $\pi$ * d.

Since we are given the circumference of the circle, 30 $\pi$ , you can find the diameter by solving for the diameter (after substituting in the circumference) in the formula for circumference.

$30\pi =\pi *d$

To cancel out $\pi$ you can divide both sides of the equation by pi. Now you have:

30 = d

Therefore the diameter of the circle is 30 inches.
