Answer:
Step-by-step explanation:
The formula of a volume of a sphere:
R - radius
We have R = 3 ?. Substitute
If the radius is 30, then the volume is:
If 30 is the length of diameter, then the radius R = 30 : 2 = 15.
Therefore the volume:
The area of flying disk is 452.16 square centimeters
Step-by-step explanation:
The disc is in circular shape so we will use the formulas for circle in this question.
Given
Circumference = C = 75.36 centimeters
We have to find the area of the disc for which we have to find the radius first.
Let r be the radius
Then
Circumference is given by:
putting the values
Dividing both sides by 6.28
The area of circle is given by:
Putting the values
Hence,
The area of flying disk is 452.16 square centimeters

Given:
The volume of the rectangular prism is
,
the height is h=(b+3)
1. The volume of a rectangular prism is (base area)*height
also, notice that the volume is a third degree polynomial, the height is a 1st degree polynomial, so the base area must be a 2nd degree polynomial, whose coefficients we don't know yet.
Let this quadratic polynomial be
2
notice that
is the product of the largest 2 terms:
and b, so m must be 1
also, notice that 12 is the product of the constants, k and 3
so k*3=12, this means k=4
3
we write the above equality again:
=
4
now compare the coefficient with the left side:
8=n+3
n=5
substituting n=5:
the base area is
Answer:
1 1/2 ft is equal to 18 inches so it is greater than 16 inches
