The diameter of the base of a right cone is 12 cm the total surface area of a cone is 306 pi cm^2 what is the length of the slan

mojhsa [17]

We know that
surface area of the cone (SA)=pi*r²+pi*r*l
where
r is the radius
l is the slant height
SA=306*pi cm²
diameter=12 cm
r=12/2----> r=6 cm
SA=pi*r²+pi*r*l--------> [SA-pi*r²]=pi*r*l----> l=[SA-pi*r²]/[pi*r]
l=[306*pi-pi*6²]/[pi*6]---> [306*pi-36*pi]/[6*pi]---> 45 cm

the answer is
<span>the length of the slant height is </span>45 cm

Solve for b. (g+l)b=n

denis23 [38]

Answer:

n

b = ---------

(g+l)

Step-by-step explanation:

We need to isolate b. Starting from (g+l)b=n, we divide both sides by (g+l), obtaining

n

b = ---------

(g+l)

Liam is saving up for a new cell phone. He uses the equation P= I + HB, where P is the cost

Stels [109]

Answer:

$H=\dfrac{P-I}{B}$

Step-by-step explanation:

Given the expression: P= I + HB

Where:

P = cost of the phone Liam is saving for.
I = amount of money he started with.
H = number of hours he babysits
B = hourly rate for babysitting.

We want to find an expression for H, the number of hours Liam will need to babysit to save enough money for a cell phone.

Our goal is to isolate the variable H in the expression P= I + HB.

P= I + HB

Subtract I from both sides

P-I=I-I+HB

HB=P-I

Divide both sides by B

$\dfrac{HB}{B} =\dfrac{P-I}{B}\\\\$Therefore\\\\H=\dfrac{P-I}{B}$

What’s the correct answer for this question?

solniwko [45]

Answer:

B.

Step-by-step explanation:

Volume of the model of moon = 4/3(πr³)

= 4/3(π)(1)³

= 4.2 feet³

Volume of cylinder = πr²h

= (3.14)(0.5)²(0.5)

= 0.39 feet³

Cylindrical clay boxes to be used = 4.2/0.39

=10.7 ≈ 11
