Volume is = to, pi x radius^2 x height. Length or diameter is the radius times 2. The radius would therefore be 6. So it comes down to
Pi x 6^2 x 5
Pi x 36 x 5
This can be easily solved in calculator

Answer:

okay let's start

Step-by-step explanation:

v = \pi \: r\: ^{2} h \\ h = 5 \: r = (12) \div 2 = 6 \\ v = \pi \times 6 ^{2}  \times 5 \\  = 565.4866776

If you purchase 27 guppies, and the increase rate of 35% per year,how many guppies will you have after 3 years
dem82 [27]

Answer:

66

Step-by-step explanation:

<u>year 1: 35% of 27</u>

convert 35% into a decimal :0.35

0.35 x 27= 9.45

27+ 9.45= 36.45 , thats what you have left at the end of year 1

<u>year 2: 35% of 36.45</u>

0.35 x 36.45= 12.7575

36.45 + 12.7575= 49.2075, thats whats left at the end of year 2

<u>year 3: 35% of 49.2075</u>

0.35 x 49.2075= 17.222625

49.2075+ 17.222625= 66.430125, thats whats left at the end of the 3rd year.

you cant have 66.430125 of a guppy so it rounds to a whole number- 66

let me know if this was helpful :)

If the circumference of a circle measures 3/2pi cm, what is the area of the circle in terms of pi?
bagirrra123 [75]

Answer:

D - Area = 9/16pi cm²

Step-by-step explanation:

in order to evaluate this question , we will first of all find the radius using the formula for finding the circumference of a circle , we will then find the area of a circle.

<u>solution</u>

given that circumference of a circle = 3/2picm

recall that the formula for finding the circumference of a circle = 2πr

3/2picm = 2πr

multiply through by 2

3picm = 4pir

divide both side by 4pi

3pi cm/4pi = r

r = 3/4 picm

Recall that the Area of  a circle = πr²

Area = pi ( 3/4)² cm

Area = 9/16pi cm²
