Step-by-step explanation:
Answer:
Perimeter =63 inches
Area = 243in²
Step-by-step explanation:
Given data
Length of computer = 18in
Width of computer = 13.5in
From the given data the computer has a rectangular shape
Perimeter of the computer = L+L+W+W= 2L+2W
Perimeter = 2(18)+ 2(13.5)
Perimeter = 36+27=63 inches
Area of rectangular shape = L*W
Area = 18 x 13.5= 243in²
We know that
the length of a circumference=2*pi*r
for D1=18 cm--------------> r1=9cm
L1=2pi*9-------> 18pi cm
for D2=6 cm-----------> r2=3 cm
L2=2pi*3-------> 6pi cm
L2/L1----------> (6pi)/(18pi)---->1/3
the answer is the option A) multiplies by 1/3
Answer:18
Step-by-step explanation:
Sin72=cosy
0.9511=cosy
Y=cos(inverse)0.9511
Y=18
