Solve a=2pir^2 2pirh for pi

1 answer:

7 0

A = 2 $\pi$ $r^{2}$ 2 $\pi$ rh |Divide by 4h $r^{3}$

$\pi ^{2}$ = $\frac{a}{4h r^{3} }$ |Square root on both sides

$\pi$ = $\sqrt{ \frac{a}{4h r^{3} } }$

Answer:

the answer is 40√3feet per second

Step-by-step explanation:

v=√16.√300

v= 4. 10√3

NB:10√3=√100 .√3=√100.3= √300

Hence v =40√3ft per second

3. f(-6) = 12+1 =13

f(-2) = 4+1 = 5

f(0) =1

Range {1,5,13}

4. f(-2) = (-2)^3+1 =-7

f(-1) = (-1)^2 +1 =0

f(3) = (3)^3 +1 = 28

Range = {-7,0,28}

5.the sequence is arithmetic

d= -11+19 = 8

an = a1 + d(n-1)

an = -19 +8(n-1)

6.l =w+5

a =l*w

a(w) =(w+5) * w

a(w)= w^2 +5w

f(w) = w^2 +5w

f(8) = 8^2 +5(8)

f(8) = 64 +40

f(8) =104 in^2

How does the precise nature of mathematics OR the imprecise nature of language sometimes get in the way of understanding problem

Degger [83]

Answer:

This is because mathematics uses some theories that helps to change words to equations. for example, a tree of height 50m makes a shadow on the ground. an observer standing at angle of 30 degrees, calculate the distance of the man to the tree. we use the the formula, tan (30)=opp/adj

$1 \div \sqrt{3 } = 50 \div x$
