Answer: 8/9 x 4/3

Step-by-step explanation:

One way to do this is, KCR. The K stand for keep, so you don't change the 8/9. the C stands for change. So, we change the division to multiplication. Lastly, the R stands for Reciprocal which means to swap the 3/4 and make is 4/3. So, we get 8/9 x4/3. Hope this helps!

A cone has a diameter of 18 in. and a height of 14 in.
Bond [772]
Cone's volume is V =  \frac{1}{3}Sh
where    S - surface area,  h - height
Surface area =  \pi r^2

r = 18/2=9
h= 14
π = 3.14
V= \frac{1}{3}  \pi r^2h= \frac{1}{3} *3.14*9^2*14= \frac{1}{3} *3.14*81*14=27*14*3.14[/tex]
V = 1186.92 in.^3

A sprinkler that sprays water in a circular area can be adjusted to spray up to 30 feet. Turning the radius-reduction screw on t
zheka24 [161]

Answer:

Area_lawn = 393.75 π ft^2

Step-by-step explanation:

Maximum radius : 30 feet

Minimum radius:  30 feet - 0.25*(30feet)  =  22.5 feet

(25 percent reduction)

To find the area of lawn that can be watered, we just need to calculate the area for the maximum radius and the minimum radius, and then subtract them.

Since the sprinklers have a circular area:

Area = π*radius^2

Max area  = π*(30 ft)^2 = 900π ft^2

Min area  = π*(22.5 ft)^2 = 506.25π ft^2

Maximum area of lawn that can be watered by the sprinkler:

Area_lawn = Max area - Min area = 900π ft^2 -506.25π ft^2

Area_lawn = 393.75 π ft^2
