Answer:The area of a circle is the number of square units inside that circle. If each square in the circle to the left has an area of 1 cm2, you could count the total number of squares to get the area of this circle.
Step-by-step explanation:The area of a circle can be found by multiplying pi ( π = 3.14) by the square of the radius.
If a circle has a radius of 4, its area is 3.14*4*4=50.24.
If you know the diameter, the radius is 1/2 as large
The answer is 200 because 508 divided by 2.54 equals to 200 inches
Answer:
∡A = 48°
∡B = 58°
∡BCA = 74°
Step-by-step explanation:
start by finding m∡BCA; this angle is supplementary with ∡BCD and the pair must add up to 180. therefore, m∡BCA = 74°
all three interior angles of a triangle must add up to 180:
74 + 4y + 3y + 22 = 180
96 + 7y = 180
7y = 84
y = 12
substitute '12' for 'y' in 3y + 22 to get 58
substitute '12' for '4y' to get 48
<span>The phone company charges 10 cents to connect a call for one minute and 8 cents per minute after that.
We call x minute to talk after the first minute.
We have 10+8x</span>≤100 (cents)
and 8x≤100-10
or 8x≤90 and x≤90:8
and x≤11.25
So: <span>How long could you talk on the phone for 1 dollar: it is 11 minute and 15 seconds</span>
