Answer:

r = 35cm

Step-by-step explanation:

Given

C = 220cm

\pi = \frac{22}{7}

Required

Determine the radius

Circumference (C) is calculated as:

C = 2\pi r

Where r represents radius

Substitute values for C and \pi

220cm = 2 * \frac{22}{7} * r

220cm =  \frac{44}{7} * r

Multiply through by 7/44

\frac{7}{44} * 220cm =  \frac{7}{44} * \frac{44}{7} * r

r = \frac{7}{44} * 220cm =

r = \frac{7 * 220cm }{44} =

r = \frac{1540\ cm}{44}

r = 35cm

<em>Hence, the radius is 35cm</em>

Combine the following fractions. <br><br> a. 3/5 + 4/15 <br><br><br> b. 5/6 - 1/4
Ne4ueva [31]

Hello there! :)

Answer:

1. \boxed{\frac{13}{15} }

2. \boxed{\frac{7}{12} }

Step-by-step explanation:

1. 3/5+4/15

First, you multiply by numerator and denominator.

3*3=9

5*3=15

=\frac{9}{15}

Then, you had to combine by the fractions.

\frac{9}{15}+\frac{4}{15}

Add by the numbers from left to right.

9+4=13

<u><em>13/15 is the final answer.</em></u>

______________________________________________

2. 5/6-1/4

First, you multiply by 2 both sides of numerator and denominator.

5*2=10

6*2=12

10/12

3/12

\frac{10}{12}-\frac{3}{12}

Subtract by the numerator.

10-3=7

<em><u>7/12 is the final answer.</u></em>

Hope this helps!

Thanks!

Have a nice day! :)

One-third of a number t is less than or equal to 5
Kryger [21]

Answer:

t ≤ 15

Step-by-step explanation:

One third of 15 is equal to five (1/3 × 15 = 5)

One third of t is lesser than or equal to five (1/3 × 5 ≤ 5)

<em>So, t cannot be more than 15.</em><em> </em><em>It</em><em> </em><em>can</em><em> </em><em>be</em><em> </em><em>equal</em><em> </em><em>to</em><em> </em><em>1</em><em>5</em><em>,</em><em> </em><em>though</em><em>.</em>

∴t ≤ 15

Given the following question where...

180 = a1+a2+a3

A triangle adds up to 180 degrees

50 + 120 = 170 + 10 = 180

The measurement of the third angle is 10 degrees or the third option.

Hope this helps.
