Answer:

[tex]SA = 70\pi[/tex]

Step-by-step explanation:

Given

See attachment for cone

Required

The total surface area

This is calculated as:

[tex]SA = \pi r\² + \pi rl[/tex]

From the attached cone:

[tex]r = 5[/tex] -- radius

[tex]l = 9[/tex] --- slant height

So, we have:

[tex]SA = \pi * 5^2 + \pi * 5*9[/tex]

[tex]SA = 25\pi + 45\pi[/tex]

[tex]SA = 70\pi[/tex]

Answer:

BD = 21 units

Step-by-step explanation:

By applying mean ratio theorem in the given triangle ABC,

[tex]\frac{AD}{BD}=\frac{BD}{CD}[/tex]

AD × CD = BD²

21 × 21 = BD²

BD² = (21)²

BD = 21

Therefore, measure of segment BD is 21 units.

Anna, Boris, and Clara thought of one number each. Anna's number increased by 20 is 21 greater than Boris's numbers decreased by 22. Boris's number decreased by 20 is 21 greater than Clara's number increased by 22. How much less is Clara's number than anna's number. Please answer fast!

Answers

Answer:

See below in bold.

Step-by-step explanation:

Let Anna's, Boris and Clara's numbers be a b and c.

a + 20 = b - 22 + 21

b - 20 =  c + 22 + 21

a + 20 = b - 1

b - 20 = c + 43

a  - b  + 20 = -1      

Adding the last 2 equations:

a  = c + 42

c = a - 42

So Clara's number is 42 less then Anna's number.

Alex, Susan and Amy shared 66 watermelons. The number of watermelons owned by Alex is two times the number of watermelons owned by Susan, while Amy has 6 more than Susan. Find the ratio of the number of watermelons owned by Susan to the number of watermelons owned by amy.​

Answers

Answer:

5:7

Step-by-step explanation:

First you have to find the watermelons owned by the three of them.

Let's take Susan as 'x'

According to the question:

1. Alex has twice the watermelons as Susan -> 2x

2. Amy has 6 more watermelons than Susan -> x+6

The sum of the watermelons is 66

SO,

x + 2x + x + 6 = 66

4x = 60

x = 15

Susan has 15

Alex has 30

and Amy has 21

Now  we do the ratio:

Susan : Amy

15    :   21

5     :    7

This diagram shows part of a regular 10 sided polygon.
Work out the size of angle marked x.

Answers

Answer:

144 degrees

Step-by-step explanation:

work out the exterior angle of the shape 360/no of sides

then take it away from 180 (angle on a straight line) leaving you with the answer

The required measure of x would be 144 degrees for the shown figure.

What is the interior Angle?

An interior angle is defined as an angle produced on the inside of a polygon by extending the sides of the polygon.

Interior angles of a polygon = (sides - 2) × 180°

This diagram shows part of a regular 10-sided polygon.

As per the question,

10x = (10- 2) × 180°

10x = 8 × 180°

10x = 1,440°

x = 1,440°/10

Apply the division operation, and we get

x = 144°

Thus, the required measure of x would be 144 degrees.
