Answer:
A
Step-by-step explanation:
It has the smallest surface with an increase in height
Answer:
127.17cm²
Step-by-step explanation:
Area of a semicircle: πr² ÷ 2
d = 18
r = 18/2 = 9
Area of a semicircle: 9²π ÷ 2 = 127.17cm²
Answer
(-6. 3) (-6, 6) (-4, 2)
Step-by-step explanation:
the solution is the dark area between the two lines.
the only trick would be if one of the points fell on the dotted line.
all points on the dotted line are not included but all points on the solid line are included.
Answer:
10 units squared
Step-by-step explanation:
Looking at the figure, we can observe that it consists of two triangles: one on the left of the y-axis and one on the right. This means that we can find the separate areas of each triangle and then sum them to get the total area.
The area of a triangle is denoted by: A = (1/2) * b * h, where b is the base and h is the height.
<u>Left Triangle</u>:
The base is 4 and the height is 4, so the area is:
A = (1/2) * b * h
A = (1/2) * 4 * 4 = (1/2) * 16 = 8 units squared
<u>Right Triangle</u>:
The base is 2 and the height is 2, so the area is:
A = (1/2) * b * h
A = (1/2) * 2 * 2 = (1/2) * 4 = 2 units squared
The total area is 8 + 2 = 10 units squared.
