Calculate the perimeter of the shape to the nearest whole number
1 answer:
Answer:
Option B
Step-by-step explanation:
Perimeter of the given figure = Sum of measures of all sides
= AB + BC + CA
Since, AB = BC = 9 cm (Radii)
CA = Length of arc CA which is the quarter of the circumference of a circle with radius 9 cm
CA =
=
=
= 14.14 cm
Now perimeter of the shape = 9 + 9 + 14.14
= 32.14 cm
≈ 32 cm
Therefore, Option B will be the correct option.

Remember
(ab)/(cd)=(a/c)(b/d)
and
1kg=1000g=1*10^3g
hmm, I estimate, 4 of them
x=number of attoms
mass of 1 times x=1*10^3
3.95*10^-22 times x=1*10^3
divide both sides by 3.95*10^-22
x=
=
=
a million has 9 zeroes
so 24 zeroes is alot that is a <span>septillion, so there are 2.5316 septillion uranium atoms in 1kg
a. 4
b. underestimate
