1. a circle has a circumfrance 88cm find its radius
2.a sector with angle 45 degrees has ab arc length 44cm find it radius and perimeter speratly
pls answer asap i will give u the brainliest
Step-by-step explanation:
Number 1
Circumference = 88cm
Circumference = 2πr
2πr = 88
πr = 88/2
πr = 44
22r/7 = 44
22r = (44 × 7)
r = (44 × 7)/22
r = 2 × 7
r = 14cm
Number 2
Length of arc = 44cm
Angle = 45°
L = ∅/360 × 2πr
44 = 45/360 × 2πr
44 = ⅛ × 2πr
44 = ¼ × πr
πr = 44 × 4
22r/7 = (44 × 4)
22r = (44 × 4 × 7)
r = (44 × 4 × 7)/22
r = 2 × 4 × 7
r = 2 × 28
r = 56cm
Perimeter = L + 2r
P = 44cm + 2(56cm)
P = 44cm + 112cm
P = 156cm

Which is a better estimate for the volume of a paper cup?
A. 12 tablespoons
B. 12 gallons
Find the value of x. 120
Answer:
x = 25
Step-by-step explanation:
2x + 70 = 120 {Subtract 70 from both sides}
2x = 120 -70
2x = 50 {divide both sides by 2}
x = 50/2
x = 25

This table gives the value of an investment for the first 5 years after the initial investment was made. The data can be modeled using an exponential function.
Years 1 2 3 4 5
Investment value $1,050 $1,103 $1,160 $1,215 $1,280
Based on the data, which amount is closest to the value of the investment 10 years after the initial investment?
$1,350
$1,475
$1,625
$1,800
Answer:
C.) $1,625
Step-by-step explanation:
Going by the numbers on the graph, you can immediately tell $1,350 and $1,475 are way too low, so cancel those out and you get $1,625 and $1,800
From here, you can see that in 5 years it hasn't gone up by far, so it won't be 1,800$ by 10 years end, making the answer clear
You can just double 280 and get 560, which the closest answer is 1,625
It's really just a high-low estimate question, 2 answers are too high or low, one is close but not really, and one is just right- or inbetween
$1,625
The amount $1625 is closest to the value of the investment 10 years after the initial investment option third is correct.
What is an exponential function?It is defined as the function that rapidly increases and the value of the exponential function is always a positive. It denotes with exponent [tex]\rm y = a^x[/tex]
where a is a constant and a>1
Let's suppose the exponential function that model the problem is:
[tex]\rm y = ae^k^x[/tex]
Plug x = 1 and y = 1050
[tex]\rm 1050 = ae^k[/tex] ...(1)
Plug x = 2 and y = 1103
[tex]\rm 1103 = ae^2^k[/tex] ...(2)
Divide equation (2) with (1)
[tex]\rm e^k = 1.0504[/tex]
Taking ln to get the value of k
k = 0.0491
a = 999.69
The exponential function:
[tex]\rm y = (999.6902)e^{0.0491}^x[/tex]
Plug x = 10 years in the above function:
y = $1633.44
Which is close to $1625
Thus, the amount $1625 is closest to the value of the investment 10 years after the initial investment option third is correct.

Step-by-step explanation:
Answer:
4, 7, 9, 12, 18, 32
Step-by-step explanation:
The sign shows that any number that is equal to, or more than, 36 is a valid answer. It can't be 3 because 3 x 9 is 27, and 27 is less than 36, so that wouldn't be true. 4 x 9 is 36, and 36 = 36, so that would be true, and obvoiusly all the other numbers that are over 4, when multiplied by 9, will equal more than 36, so they are all correct, except for the 3 and none answers. I hope this helps you out :)

Find each value or measure. Assume that segments that appear to be tangent are tangent. Find QS
Answer:
arc QS = 104°
Step-by-step explanation:
arc QTS = 2(128) = 256
arc QS = 360 - 256 = 104°
The measure of arc length QS is 104.
We have,
An inscribed angle is an angle whose vertex is on the circumference of a circle, and its sides are chords of the circle.
From the definition,
Inscribed angle = 1/2 x intercepted arc
Now,
128 = 1/2 x QTS
QTS = 256
Now,
QTS + QS = 360
256 + QS = 360
QS = 360 - 256
QS = 104
Thus,
The measure of QS is 104.
