Answer:1384.74 square inches
Step-by-step explanation:
Diameter=42 inches
Radius=42/2
Radius=21 inches
π=3.14
area of circle=π x radius x radius
Area of circle=3.14 x 21 x 21
Area of circle=1384.74 square inches
Answer:
TU = 46
Step-by-step explanation:
Here, we are concerned with finding TU
Mathematically;
Since U is between T and B, by convention;
TB = TU + UB
Substituting the values so we can find x;
55 = 6x + 16 + 2x -1
55 = 6x + 2x + 16-1
55 = 8x + 15
8x = 55-15
8x = 40
x = 40/8
x = 5
But TU = 6x + 16; substitute the value of 5 for x
TU = 6(5) + 16
TU = 30 + 16
TU = 46
Answer:
It would cost $2.20
Step-by-step explanation:
If 3 cans = $.55
then 3*4 = 12
soooo 4*.55 = 2.20
Hope this helps!!!
Answer:
10 1/2
Step-by-step explanation:
First you would do.
9+2/3+5/6
2/3=4/6
9+4/6+5/6
9+9/6=3/2
9+1 1/2
=10 1/2
Answer: the polygon has 20 sides.
Step-by-step explanation:
The formula for determining the sum of the measure of the interior angles in a regular polygon is expressed as (n - 2) × 180.
if the sum of the measures of the interior angles is 3960
degrees. This means that
(n - 2) × 180 = 3960
Expanding the brackets by applying the distributive property, it becomes
180n - 360 = 3960
180n = 3960 - 360
180n = 3600
Dividing both sides by 180, it becomes
n = 3600/180
n = 20
