Answer:
C = 21.98 ft^2
A = 38.465 ft^2
Step-by-step explanation:
The diameter is 7 ft
The radius is 1/2 of the diameter so 1/2 *7 = 3.5 ft
Circumference = pi*d
C =pi* 7
C =3.14 *7
= 21.98 ft^2
A = pi*r^2
= 3.14 (3.5)^2
= 3.14 (12.25)
= 38.465 ft^2
Answer:
the number of boys and girls on a team is 58 and 26 respectively
Step-by-step explanation:
Given that
Total members in swimming team is 84
Let us assume the number of girls be x
so, the number of boys would be
y = 2x + 6
Now the equation is
x + y = 84
x + 2x + 6 = 84
3x = 78
x = 26
And, y = 2 × 26 + 6
= 52 + 6
= 58
Hence, the number of boys and girls on a team is 58 and 26 respectively
Answer:
1/10
Step-by-step explanation:
first you find the common denominator.
multiply 1/2 by 5 and 2/5 by 2
now you have 5/10-4/10
now its easy and the answer is 1/10
Answer:
Undefined
Step-by-step explanation:
Use the formula y2-y1/x2-x1
3-9/-5-(-5)
-6/0
Any number with a denominator of 0 is undefined
Answer:
Electromagnetic waves have crests and troughs similar to those of ocean waves. The distance between crests is the wavelength. The shortest wavelengths are just fractions of the size of an atom, while the longest wavelengths scientists currently study can be larger than the diameter of our planet!
