The shape is a square pyramid, meaning it has one square face and four triangle faces of equal area. Add these areas together to get the total surface area.
Area of Square + 4*Area of Triangle = SA
Area of Square:
2^2=4
Area of Triangle:
0.5*2*3=3
SA=4+4*3
SA=16 meters squared
A rectangular garden has a length of 5ft and a width of 8 ft. The length is increased by 2 feet. By how many square feet does the area increase?
Step 1. Area of a rectangle is given as A=length * width
Step 2. Then, A1=5*8=40 square feet of original area of rectangular garden.
Step 3. Then, A2=(5+2)*8=56 square feet since the length is increased by 2. feet.
Step 4. Difference = A2 - A1 = 56 - 40 = 16 square feet.
Step 5. ANSWER: The area increased by 16 square feet.
Answer:
First answer is correct
Step-by-step explanation:
pi*r^2
use formula and substitute
r is the radius so half the diameter

(d) see attached
Step-by-step explanation:
A linear function has equally-spaced outputs for equally-spaced inputs. The given tables all have sequential values for x, so we can find the linear function by looking at the differences of y-values.
a) 2 -1 ≠ 4 - 2 . . . . not linear (exponential)
b) 1 -0 ≠ 3 -1 . . . . not linear (quadratic)
c) 1 - 0 ≠ 0 - 1 . . . . not linear
d) 3 -1 = 5 -3 = 7 -5 . . . . a linear function
