Cheyenne dibujó un círculo con diámetro 1 metro. Midió la circunferencia para estimar el valor de Pi. Complete la tabla y, a continuación, escriba una ecuación para encontrar la circunferencia C, para un círculo con diámetro d.
Diámetro, d (metros) 1 2 3 4
Circunferencia, C (metro) 3.14

The answer is in the image 

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg

Approximately it is aqual to 1300kg

The wood before starting =12 feet

Left wood=6 feet

Wood used till now=12-6=6 feet

Picture frame built till now= 6/(3/4)

=8 pieces

Therefore, till now 8 pieces have been made.

The answer is in the image 

There are 6 outcomes 1,2,3,4,5,6

Total outcomes = 6

Outcomes when rolling a number is 4 or less = 1,2,3,4

Total outcome when rolling a number is 4 or less=4

Probability = required outcome/total outcome

                 =4/6

                 =2/3

Therefore probability = 2/3

Total fabric purchased = 1 1/4 = 5/4

Fabric used = 3/4

Fabric left = 5/4 - 3/4

                 = 2/4

                 =1/2 yard

III is the case of joint variation as Area A depends on l and w

In I and II it depends on s and r respectively as pi is constant

Volume of pool = 1472 m^3

Length = 36.8m

Breadth = 20m

We know,

Volume = l*b*h

1472 = 36.8 * 20 * h

h = 1472/736

h = 2m

Pool is 2m deep

Speed = distance/time

distance = 60 feet

time = 30 sec

speed = 60/30

          =  2 feet/sec

Volume of rectangular prism = length * breadth * height

Given,

Length = 6 cm

height = 1 cm

Width = 4 cm

Volume = 6 * 1 * 4

=24 cm^3
