Volume= length x width

So the length and width are 13 so 13x13= 169 but it says ROUND to the nearest whole number so 169 rounded to the nearest whole number is 170. So your answer is 170. I hope this helps

Find the midpoint P(16,7) and Q(12, -3) With work.

hichkok12 [17]

Answer:

(14, 2 )

Step-by-step explanation:

Use the midpoint formula

[0.5(x₁ + x₂), 0.5(y₁ + y₂) ]

with (x₁, y₁ ) = (16, 7) and (x₂, y₂ ) = (12, - 3)

midpoint = [0.5(16 + 12), 0.5(7 - 3) ] = [0.5(28), 0.5(4) ] = (14, 2 )

Find the volume of a right circular cone that has a height of 9.1 m and a base with a circumference of 12.1 m. Round your answer

Orlov [11]

Answer:

$V=35.3\ m^3$

Step-by-step explanation:

-Given the cone's height is 9.1m and the Circumference is 12.1

#We use the circumference formula to calculate the radius:

$C=2\pi r\\\\12.1=2\pi r\\\\r=\frac{12.1}{2\pi}=\frac{6.05}{\pi}\ cm$

-The volume of the cone using the radius above can then be calculated as follows:

$V=\pi r^2\frac{h}{3}\\\\=\pi\times(\frac{6.05}{\pi})^2\times \frac{9.1}{3}\\\\\\=35.3\ m^3$

Hence, the cone's volume is $35.3\ m^3$

Can someone please help me solve this, thank you so much if u help!

malfutka [58]

Answer:

68°

Step-by-step explanation:

The triangle containing the 79° angle is isosceles. That means the other base angle is also 79°. The central angle is ...

V = 180° -2(79°) = 22°

Angle X is the other acute angle in right triangle VWX, so has measure ...

X = 90° -22° = 68°

_____

Additional comment

A tangent makes a right angle with the radius to the point of tangency. W is the point of tangency, so angle VWX is a right angle.

So far, 18 of the 25 students in your class have turned in field trip permission slips. What percent of your classmates have tur

aleksklad [387]

Solution:

we are given in the problem that

So far, 18 of the 25 students in your class have turned in field trip permission slips.

we have been asked to find

What percent of your classmates have turned in permission slips?

Required Percentage $=\frac{18}{25}*100\\$

Simplify we get

Required Percentage $=\frac{18}{25}*100=18*4=72\\$

Hence 72% percent of your classmates have turned in permission slips.
