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]
