Find the volume of a cone with a base radius of 6 cm and a height of 10 cm write in terms of pie
Savatey [412]

Answer:

  • <u>Volume of the cone is 120 π cm³ </u>

Step-by-step explanation:

Given that Base radius of cone is 6 cm and height is 10 cm and we need to find volume of the cone. Volume of cone is given by:

\\ \:  \:    \dashrightarrow \:  \:  \: \underline{\boxed{\pmb{\sf{Volume_{(cone)} = \dfrac{1}{3} \pi r^2 h }}}}  \\ \\

On Substituting the required values, we get:

\\ \:  \: \dashrightarrow \:  \:  \sf \: Volume_{(cone)} =  \frac{1}{3}  \times  \pi \times  {(6)}^{2}  \times 10 \\  \\  \\  \:  \: \dashrightarrow \:  \:  \sf \: Volume_{(cone)} = \frac{1} {\cancel{3}}  \times  \pi \times  \cancel{36} \times 10 \\ \\   \\  \:  \: \dashrightarrow \:  \:  \sf \: Volume_{(cone)} = \pi \times 12 \times 10 \\  \\  \\  \:  \: \dashrightarrow \:  \:  \sf \: \: { \purple{Volume_{(cone)} =120 \pi \: cm^3 }}\\  \\

A countertop is 16 feet long and 3 feet wide. what is the area of the countertop in square meters.
Mrac [35]
Area=legnth times width
legnth=16 ft
width=3 ft
but wait, they want the area in squazre METERS
so convert feet to meters
1 foot=0.3048 meters

convert 16 feet and 3 feet to meters

16 feet=16 times 0.3048=4.8768
3 feet=3 times 0.3048=0.9144

so the area is now
legnth=4.8768 m
width=0.9144m

area=4.8768 m times 0.9144 m=4.45934592
round
4.0
answer is 4 square METERS

4 m^2

Two cards are drawn without replacement from a standard deck of 52 playing cards. What is the probability of choosing a red card
joja [24]

Answer: \dfrac{3}{51}

Step-by-step explanation:

Given : The total number of cards in a deck = 52

Number of red cards = 26

There are two types of red  cards : diamond and heart.

Number of diamond cards = 13

The probability that the first card is a diamond :-

\dfrac{13}{52}=\dfrac{1}{4}

Since diamond is also a red card.

Now, the total cards left = 51

The number of red cards left = 12

The probability that the second card is a red card (without repetition) is given by :-

\dfrac{12}{51}

Now, the probability of choosing a red card for the second card drawn, if the first card, drawn without replacement, was a diamond :-

\dfrac{1}{4}\times\dfrac{12}{51}=\dfrac{3}{51}
