suppose your average, after taking 4 quizzes is 70 out of 100. what must your average be on the next 4 quizzes to increase your

exis [7]

Answer:

94

Step-by-step explanation:

Average = Total / Number of Data

$70 \times 4 = 280$

You have a total of 280 points after 4 quizzes.

4+4=8 quizzes in total

Total you need for average to be 82

$82 \times 8 = 656$

Number of points you need to hit required:

$656 - 280 = 376$

You need 376 points in total for the next 4 quizzes.

$376 \div 4 = 94$

You need an average of 94 points on the next 4 quizzes.

What's the circumference of a circle that is 9cm? Please explain step by step of how you got the answer...

Sauron [17]

Formula for finding circumference of a circle is 2πr.

Step-by-step explanation:

The given question says what is the circumference of a circle that is 9cm.
As radius is required for finding circumference of a circle, the formula is 2πr.
Therefore taking the formula and substituting radius (r)= 9 cm. We get 2πr as 2×π×9 = 18π cm OR

If we substitute the value of π as 3.14 we will get⇒ 2×3.14×9= 56.52 cm.
So the circumference of the given circle would be 18π or 56.52 cms.

A cylinder has volume 78 cm3 . What is the volume of a cone with the same radius and height? A 26 cm3 B 39 cm3 C 156 cm3 D 234 c

otez555 [7]

Answer:

Option A - $26 \mathrm{cm}^{3}$

Step-by-step explanation:

Given: The volume of a cylinder = $78 \mathrm{cm}^{3}$

Let us substitute the volume of cylinder in the formula.

The formula for volume of a cone is $V=\frac{\pi r^{2} h}{3}$ (1)

The formula for volume of a cylinder is $V=\pi r^{2} h$ (2)

Substituting $V=78$ in equation (2), we get,

$\begin{array}{c}{V=\pi r^{2} h} \\{78=\pi r^{2} h}\end{array}$

Given that the cone has the same radius and height of that of the cylinder, let us substitute $78=\pi r^{2} h$ in equation (1)

$\begin{array}{l}{V=\frac{\pi r^{2} h}{3}} \\{V=\frac{78}{3}} \\{V=26}\end{array}$

Thus, the volume of a cone with the same radius and height of a cylinder is $26 \mathrm{cm}^{3}$ .
