The picture contains two geometric objects: semicircle and right triangle
First, find the area of semicircle
This is the formula for area of semicircle
a = 1/2 × area of circle
a = 1/2 × π × r²
Before we find the area, we should determine the value of r. Given from the question that the diameter is equals to 8 m. Radius (r) is half of diameter (d)
r = 1/2 d
r = 1/2 × 8
r = 4 m
Caculate the area
a = 1/2 × π × r²
a = 1/2 × 3.14 × 4²
a = 1/2 × 3.14 × 16
a = 1/2 × 50.24
a = 25.12 m²
Second, find the area of the right triangle
The formula is
a = 1/2 × b × h
Given from the question that the base (b) is 12 m, and the height (h) is 8 m.
Calculate the area, input the value of b and h to the formula
a = 1/2 × b × h
a = 1/2 × 12 × 8
a = 1/2 × 96
a = 48 m²
Third, sum both area
a = area of semicircle + area of right triangle
a = 25.12 + 48
a = 73.12 m²
Solution:
The area is 73.12 m²
When you change a slope from positive to negative, it flips because it goes from being an increasing slope to a decreasing slope. negative slopes decrease as they move from left to right; positive slopes increase from left to right. in the case of y = x, which is line directly through the origin, this line is steadily increasing from the bottom left corner to the top of the right corner of a graph. when you change the slope from 1 to -1, the graph instead declines from the top left to the bottom right.
Step-by-step explanation:
im pretty sure ur supposed to find so the answer woild be c=0.8
Answer:
7x + 2y + 8
