Answer:

72

Step-by-step explanation:

Circumference of a circle = 2πr

Area of a circle: πr^2

Plug in:

C = 2πr

30.1 = 2(3.14)r

30.1 = 6.28r

r = 4.79 (Dividing both sides by 6.28)

Use area of the circle:

A = 3.14(4.79)^2

= 72.044474

Round to nearest whole number = 72

Find the volume please and Katie, why are you deleting my questions?

Volume of the prism = 75 cubic feet

Solution:

The image given is a rectangular prism (or) a cuboid.

Area of base = l × b = 25 square feet

Height of the prism = 3 feet

Volume of the prism = l × b × h

                                  = (l × b) × h

                                  = 25 × 3

                                  = 75 cubic feet

Volume of the prism = 75 cubic feet

Hence, the volume of the prism is 75 cubic feet.

Hello from MrBillDoesMath!

Answer:   factor = 4

Discussion:

Look at the sequence of numbers


1/64,  1/16,    1/4,    1,   4


It's seems clear that multiplying a term by 4 gives the next term in the sequence.


Thank you,

MrB

A rectangular countertop has a perimeter of 24 feet. its area is 27 square feet. what are the dimensions of the counter?
Kaylis [27]
You can solve this by setting up 2 equations and solving quadratically.

perimeter of a rectangle is found by the formula 2*base + 2*height = perimeter.
area is found by base*height=area.
2b+2h = 24 and b*h=27 solving one equation for base or height and substituting in the other equation will give us an equation we can use for this particular problem. solving b*h=27 for b will give us b= 27/h. substituting this into the perimeter equation we get 2(27/h) + 2h = 24. If we use algebra to manipulate the equation we get 24-2h= 2(27/h) so 24-2h = 54/h multiplying both sides by h give (24-2h)h = 54 moving the 24h-2h^2 to the other side gives 0 = 2h^2-24h+54 solving the quadratic for h gives (2h+6)(h+9)=0 so solving for h we get h=6/2 = 3 or    h=9 is we use h =9 and plug it into the original equation for 2b+2h=24 then we get 2b+2(9)= 24 so then 2b = 24-18 so b = 6/2 =3. so we get 2(3)+2(9)=24 so 6+18=24 for perimeter and for b*h=27 we get 3*9=27 so the dimensions are 3x9 3 is the shorter side and 9 is the longer side = 3x9
