Step-by-step explanation:
the perfect squares =
81, 121, 625
Answer:
82.97cm^2
Step-by-step explanation:
Given data
Circumference= 131.88 centimeters
We want to find the area of 6/10 part of a circle
Firstly, let us find the area of the circle
We need to get the radius
C= 2πr
131.88= 2*3.142*r
131.88=6.284r
r= 131.88/6.284
r=20.98 cm
Area= πr^2
Area= 3.142*20.98^2
Area= 3.142*440.16
Area= 1382.98cm^2
Hence 6/10 of a 1382.98
=0.06*1382.98
=82.97cm^2
Answer:
a) 121,000
b)8.35 x 10^-6
Step-by-step explanation:
Answer:
n=6
Step-by-step explanation:
(n-18)/3 = -4
multiply by 3
n-18 = -12
add 18
n = 6
I believe notation one would be 8:9 and notation two would be 8 to 9
