To work out the volume of a prism, you multiply the area of cross-section by the height (or length).

So for a cylinder, you work out the area of the circle and then multiply it by the height.

Area of circle (or cross-section) = π × radius²

= π × 0.7²

= 0.49π m²

Now to get the volume of the cylinder, you times this area of the cross-section by the height of the cylinder:

Volume = 0.49π × 1.5

= 2.3 m³ (accurate to 2 decimal places)

Answer:

The maximum volume of rainwater the cylinder can hold is:

2.3 m³

A gene can be either type A or type B, and it can be either dominant or recessive. If the gene is type B, then there is a probab

WARRIOR [948]

Answer: The probability that a gene is of type A is 0.29.

Step-by-step explanation:

Let A be the event of type A.

Let B be the event of type B.

Let D be the event of dominant.

So, P(B and D) = 0.22

P(D|B)=0.31

So, Using the conditional probability, we get that

$P(B|D)=\dfrac{P(B\cap D)}{P(B)}\\\\0.31=\dfrac{0.22}{P(B)}\\\\P(B)=\dfrac{0.22}{0.31}=0.71$

So, the probability that a gene is of type A is given by

$P(A)=1-P(B)=1-0.71=0.29$

Hence, the probability that a gene is of type A is 0.29.

In the roof truss, line BG bisects ∠ABC and ∠DEF, m∠ABC= 112°, and ∠ABC≅∠DEF.

Dennis_Churaev [7]

In the given diagram, line BG bisects ∠ABC and ∠DEF, m∠ABC= 112°, and ∠ABC≅∠DEF. So the measure of angles are :

1. m∠DEF= 112° because ∠ABC≅∠DEF

2. m∠ABG= 56° because a straight line BG is bisecting ∠ABC in two equal parts. So, $\frac{112}{2} = 56$

3. m∠CBG= 56° because ∠ABG and ∠CBG are equal.

4. m∠DEG= 56° because ∠ABG ≅ ∠DEG

the graph of g(x) is a translation of the function f(x) = x2. the vertex of g(x) is located 5 units above and 7 units to the rig

bulgar [2K]

Translation of 7 units to the right ⇒ subtract 7 units to the argument ⇒ f(x-7)

Translation of 5 units up ⇒ add 5 units to the function ⇒ f(x) + 5

g(x) = f (x-7) + 5 = (x-7)^2 + 5

The subtraction of 7 units to the argument of the function (this is x) translates the function 7 units to the right.

Adding 5 units to the function f, translates the graph 5 units up.

You buy a new laptop for $300. The sales tax is 6%. What is the total cost for the laptop including the sales tax?

ladessa [460]

Answer: Total cost incurred on new laptop is $318.

Explanation:

Since we have given that

Cost price of new laptop = $300

Sales tax = 6%

total cost of laptop including the sales tax is given by

$Cost\times \frac{100+\text{ sales tax}}{100}$
