Answer:
The area of circle A is 16 times the area of circle B.
Step-by-step explanation:
he area of circle A is three times the area of circle B.
It depends on the value of π.
It depends on the actual diameters of the circles.
The area of circle A is 16 times the area of circle
the circumference of a circle = 2 x pi x r
Let imagine that the radius of B is 2cm
then the circumference of B = 2 x 2 x pi = 4pi
If the circumference of a is 4 times that of B, it means the circumference is 16 and the radius is 8
Area of a circle is pi x r^2
Area of B = pi x 2^2 = 4pi
Area of A = pi x 8^2 = 64pi
64/4 = 16 pi

Answer:
q = 2√14
Step-by-step explanation:
To determine the value of q, apply the leg rule/geometric mean theorem, which is:
Hypotenuse/leg = leg/part
Hypotenuse = 10 + 4 = 14
Leg = q
Part = 4
Plug in the values into the equation:
14/q = q/4
Cross multiply
q*q = 14*4
q² = 56
q = √56
q = √(4*14)
q = 2√14
Answer:
A
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (1, 0) , thus
y = a(x - 1)² + 0
To find a substitute the coordinates of the y- intercept (0, 1) into the equation
1 = a(- 1)² = a , thus
a = 1
y = (x - 1)² → A
Answer:
Federalists wanted a
centralized banking
system and Alexander
Hamilton, as Secretary of
the Treasury, proposed a
national bank in 1789.
• Antifederalists, like
Thomas Jefferson,
opposed this plan.
– They favored a
decentralized banking
system in which states
established and
regulated banks within
their borders.
Step-by-step explanation:
Answer:
Rate of jogging is 4.6 miles per hour.
Step-by-step explanation:
Rachel jogs 20 feet in 3 seconds and we have to find the rate of jogging in miles per hour.
Since 1 feet = 0.000189394 miles
Therefore, 20 feet = 0.0037879 miles
Similarly, 1 second = 
hour
Therefor, 3 seconds = 
= 
hours
Formula to calculate the rate = 
= 
= 1200 × 0.0037879
= 4.545
≈ 4.6 miles per hour
Therefore, rate of jogging is 4.6 miles per hour.
