What is the surface area of the regular pyramid given below?
A. 280 units2
B. 329 units2
C. 189 units2
D. 140 units2
Answers
The surface area of the regular pyramid in the diagram is 189 units². The correct option is C. 189 units²
Area of a PyramidFrom the question, we are to calculate the surface area of the regular pyramid
The surface area of the pyramid = Sum of area of the triangular faces + Area of the square base
∴ Surface area of the pyramid = [tex]4(\frac{1}{2}bh)+ b^{2}[/tex]
Surface area of the pyramid = 2bh + b²
Where b is the base
and h is the perpendicular height of each triangular faces
In the given diagram,
b = 7
h = 10
∴ Surface area of the pyramid = 2×7×10 + 7²
Surface area of the pyramid = 140 + 49
Surface area of the pyramid = 189 units²
Hence, the surface area of the regular pyramid in the diagram is 189 units². The correct option is C. 189 units²

Answers
The diagram of x + 3 and 2x are as drawn in the image attached
How to draw a diagram of x + 3 and 2x?Given the situations: x = 1, x = 2, x = 3 and x = 4
For x + 3
x = 1, x+3 = 4
x = 2, x+3 = 5
x = 3, x+3 = 6
x = 4, x+3 = 7
For 2x
x = 1, 2x = 2
x = 2, 2x = 4
x = 3, 2x = 6
x = 4, 2x = 8
You will use the values of x and y = x+3, and the values of x and y = 2x to draw the diagram of the lines as shown in the attached image

MARKING YOU BRAINLIST AND 5 STARS! A tire from Karen's car is shown below. Which is the closest to the distance traveled, in feet, after 3 full rotations of the tire? The diameter is 2 feet, by the way.
Answers
Answer:
18.86 feet
Step-by-step explanation:
One rotation of the tire is equal to the circumference of the tire
The formula for circumference of a circle (remember that a tire is shaped as a circle) = πd
where
π = 22/7
d = diameter
The size of one revolution = 2 x 22/7 = 44/7 feet
The distance covered in one rotation of the tire is 44/7 feet
The distance covered in 3 rotations = (44/7) x 3 = 18.86 feet
