Ian needs to find the area of the shaded region shown below. Which statements can he use to find the answer? Select three options.

A circle with diameter 11 feet. Three-quarters of the circle is shaded.
The radius is 5.5 feet.
The area of the whole circle is A = (5.5) squared pi.
The area of the whole circle is A = (11) squared pi.
The area of the shaded region can be found by multiplying the area of the whole circle by three-fourths as in A = three-fourths (pi times r squared).
The area of the shaded region can be found by multiplying the area of the whole circle by two-thirds as in A = two-thirds (pi times r squared).

HELP PLZZ I FORGOT HOW TO DO THIS!!!! What is the surface area of the square pyramid represented by the net?



Enter your answer in the box.

Answers

Answer:

39[tex]ft^{2}[/tex]

Step-by-step explanation:

Area of a triangle = [tex]\frac{1}{2}[/tex] × base × height

All four triangles are similar. So finding the area of one triangle, will be the area of the other triangles.

 [tex]\frac{1}{2}[/tex] × 3 × 5 = 7.5[tex]ft^{2}[/tex]

∴ The area of 4 triangles are 7.5 × 4 = 30[tex]ft^{2}[/tex]

Then the only shape remaining is the square.

Area of the square = [tex]length^{2}[/tex] (all the sides of a square are equal)

= [tex]3^{2}[/tex] = 9[tex]ft^{2}[/tex]

Total surface area = 30 + 9 = 39[tex]ft^{2}[/tex]

Hi there! Let's start off with PEMDAS. It would appear that there are no parentheses or exponents, so let's get to that | Absolute Value |. -4 + 0 is -4, but because it's an absolute value, it'll become 4. The problem should read as 6/2*4. Let's move on to Multiplication/Division. 6/2 is 3, and multiplying 3 by 4 is 12.

In 1777, Boyrereau Brinch, an enslaved African, joined the Continental Army. In 1783, he was honorably discharged and, because of his military service, freed from slavery. I also entered the banners of freedom. Alas! Poor African Slave, to liberate these freemen, my own tyrants. I went into Capt. [Samuel] Grangers company. We marched to Frog Plain, from there to Second Hill between Reading and Ridgold. General Worcester commanded the British under the command of General Howe, who attacked us. We beat them back; the fight was continued all day, and the victory was sometimes doubtful. Finally, I was in the battles at Cambridge, White Plains, Monmouth, Princeton, Newark, Frogs Point, Horseneck where I had a ball [bullet] pass through my knapsack. All of which are battles the reader can obtain a more perfect account of from history than I can give. At last we returned to West Point and were discharged, as the war was over. Thus was I, a slave for five years fighting for liberty. After we were disbanded, I returned to my old master at Woodbury [Connecticut], with whom I lived one year, my services in the American war having emancipated me from further slavery and from being bartered or sold.
