1. Find the area and perimeter. NOTE: the top is a semi-circle (half-circle).
20 mm
14 mm
32 mm

Semicircle =

semicircle =

semicircle = 51.4

∴ the perimeter is 14 + 32 + 51.4

∴ The perimeter is 97.4 cm

Area 1 =

Area 1 = 20 ÷ 2 = 10

Area 1 =

Area 1 = 314.2

Area 2 = 14 × 32 = 448

Area = Area 1 + Area 2

Area = 762.2cm²

Step-by-step explanation:

answer: slight chance that it will happen

step-by-step explanation:

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
