Answer:
the square pyramid has a base that is 4 units on each side. The height of each triangular face is 4 units.
Step-by-step explanation:
for the base count the boxes on one side. For the height count from the base of the pyramid to the point of the triangular faces.
Answer:
Blank 1: Four
Blank 2: Three
Step-by-step explanation:
You can solve both by looking at the graph, no formulas needed.
Blank 1: The base is the square in the middle (in this case). If you're ever unsure, the name of the shape usually names the base. It's called a "square pyramid" which means the base is square.
Now, we know it's just asking for how many units each side of the square is. Because this is a square, all sides are the same, so the amount of units is the same. If you count the units on one side, it's four.
Blank 2: The "triangular face" just means the triangle. The height of the triangle is found by counting the units of the tallest part. The tallest part is the middle. The middle is 3 units tall.
Hope this helped!

Answer:
A. 18.84
B. 28.26
C. 364.24
D. 120
E. 14
F. 21
G. 96
CODE: 1977.98
Step-by-step explanation:
a. C = 2πr
C = 2π(3)
C = 6π
C = 6(3.14)
C = 18.84
b. A = πr²
A = π(3)²
A = 9π
A = 9(3.14)
A = 28.26
c. C = 2π(58)
C = 116π
C = 116(3.14)
C = 364.24
d. 4x + 2x = 180
6x = 180
x = 30
4x = 4(30) = 120
e. 3x - 21 = x + 7
2x = 28
x = 14
f. angle JHK = 3x - 21 = 3(14) - 21 = 21
g. supplementary means 2 numbers add up to 180
180 - 84 = 96
CODE: E(C - D) - F(G - B) - A
14(364.24 - 120) - 21(96 - 28.26) - 18.84
= 14(244.24) - 21(67.74) - 18.84
= 3419.36 - 1422.54 - 18.84
= 1977.98
