A cone has volume 12pie cubic inches. Its height is 4 inches. What is its radius?
A.) 6 inches
B.) 4 inches
C.) 12 inches
D.) 3 inches​

Answers

Answer 1

Answer:

r = 3

Step-by-step explanation:

The formula of a volume of a cone

V= 1/3 pie r^2 H

r - radius

H - height

We have V = 12π in³ and H = 4 in. Substitute:

A Cone Has Volume 12pie Cubic Inches. Its Height Is 4 Inches. What Is Its Radius?A.) 6 InchesB.) 4 InchesC.)
Answer 2

The radius of the cone is 3 inches

Volume of a conev = 1 / 3 πr²h

where

h = height

r = radius

Therefore,

v = 12π

h = 4

12π = 1 / 3 × π × r² × 4

12 = 4  /3  r²

36 = 4r²

r² = 36 / 4

r = √9

r = 3 inches

Westminster Street and Lake Avenue intersect. If Westminster Street is 7 meters wide and Lake Avenue is 5 meters wide, what is the distance between two opposite corners of the intersection? If necessary, round to the nearest tenth.

Answers

Answer:

the distance between two opposite corners of the intersection is 8.60 meters

Step-by-step explanation:

The computation of the distance between two opposite corners of the intersection is given below:

Here we applied the Pythagoras theorem

[tex]= \sqrt{7^2 + 5^2} \\\\= \sqrt{49 + 25} \\\\= \sqrt{74}[/tex]

= 8.60 meters

hence, the distance between two opposite corners of the intersection is 8.60 meters

3. Elena walked 12 miles. Then she walked 0.25 that distance. How far did she walk all together? Select all that apply.
A. 12 + 0.25 ⋅ 12
B. 12(1 + 0.25)
C. 12 ⋅ 1.25
D. 12 ⋅ 0.25
E. 12 + 0.25

Answers

Answer:

A, B, C

Step-by-step explanation:

12+0.25*12=12(1+0.25)=12*1.25

Answer:

B. 12 + 0.25 ⋅ 12

C. 12(1 + 0.25)

Step-by-step explanation:

It asks you how far she walks all together, so you need to find that answer first to figure out the rest correctly. Now, the total she walked is 15 miles. B. and C. give you 15, however, the rest give you different answer than the total she actually walked.

David and his 2 children are going to the zoo.
The administration price is
Adult:£60
Children:£67
FAMILY DISCOUND CARD GIVES
1/5 off adults price
60% off child price
Work out the total price David pays after using his discount card.

Answers

Answer:

£92.40

Step-by-step explanation:

Discount price for David =1/5 of 60

= 1/5 × 60/1

= £12 (5 multiplied by 12 is 60)

Price for one child = £67

Price for 2 children= £67 × 2

= 134

Therefore discount price for the children,

134 × 60/100

= 134 × 6/10

= 134 × 3/5

= 26.8 × 3

= 80.4

= £80.40

Therefore total Price David pays,

£80.40 + £12

= £92.40

Mode: The mode is the element that occurs most in the data set. In this case, all elements occur only once, so there is no mode.

Median: Arrange the data in an ascending order and the median is the middle value. If the number of values is an even number, the median will be the average of the two middle numbers.

Answer:

Mode: no mode

No mode because there are no repeating numbers.

Find the equation of the line: which passes through (1,-7) and is perpendicular to (-4,6) and (5,-3)

Answers

Answer:

-9 6 that is because the line has to be perpenducular to the other line

Step-by-step explanation:

Slope of line between points (-4, 6) and (5, -3)

=> Rise / Run

=> [6 - (-3)] / [(-4) - 5]

= 9 / (-9)

= -1.

Thus slope of perpendicular line

= -1 / (-1) = 1.

We have y = x + c.

When x = 1, y = -7.

=> (-7) = (1) + c, c = -8.

Hence y = x - 8.
