What is the similarity ratio of a smaller cone with a height of 9 and a radius of 6 and a larger cone with a height of 15 and a radius of 10?
The smaller to the larger is a ratio of 6:10 or 3:5
When you make the circle bigger or smaller which number of thte standard equation for a circle centered at the origin changes?
The Radius
What is the radius of the circle equal to?
Radius of a circle= Perimeter of the circle/2*pi Radius is half the diameter Radius is the length of a straight line from the center point of the circle to the edge of the circle.
If the radius of a circle with an area of 120 mm squared is multiplied by 3 what is the area of the new circle?
In ratios, the ratios of areas is the square of the ratio of sides. Consider the original circle and the new larger circle formed by multiplying its radius (length) by 3: The circles have lengths in the ratio 1 : 3 → the circle have areas in the ratio 1² : 3² = 1 : 9 → The larger circle's area is 9 × 120 mm² = 1080 mm²

What is a circle with a little circle in it called?
An annulus. Area = pi (R2 - r2) when R is radius of larger circle and r is radius of smaller circle.
In the two circles shown below the radius of the larger circle is three times the radius of the smaller circle If the area of the larger circle is 60.84 timmespi what is the area of the smaller circle?
if the radius is a third then the area is a ninth 60.84 x 1/32 = 6.76 timmespi (if that's 'times pi' then) 6.76/pi = 2.15
What A circle with a radius of 3 cm shares a center with another circle that has a radius of 5 cm. Find the probability that a randomly selected point is in the larger circle but not in the smaller ci?
We can look at total areas (and ignore units-they're all the same). The smaller circle has an area of 9pi, and the larger circle has an area of 25pi. The smaller circle is entirely inside of the larger circle. So anything not in the smaller circle is in the larger circle. 16pi square centimeters are part of only the larger circle. 16pi/25pi=.64. So the desired probability is .64.
What is the perimeter of a circle with a radius of 15 inches?
Larger than a whale yet smaller than an ant
What is the definition of radius?
The radius is the distance from the center of a circle to the circle itself or its perimeter (one half the diameter).The radius is also the name of the smaller of the two bones of the human forearm. The longer, larger bone is called the ulna.
What is the probability as a fraction that a point chosen at random within a circle of radius 10 cm will be inside a concentric circle of radius 4 cm?
The probability as a fraction that a point chosen at random within a circle of radius 10 cm will be inside a concentric circle of radius 4 cm is the ratio of the area of the smaller circle (4 cm radius) to the area of the larger circle (10 cm radius). Therefore, the probability is (4^2)/(10^2) = 16/100 = 4/25.
What operation do you use if you want to change a larger unit into a smaller unit?
In a given circle, the radius is 9 cm. What is diameter?
Radius of the smaller circle has to be 40 per cent as large as the smaller circle 5ft. What circumference of the larger circle should be?
.4r=5 r=5/.4 r=12.5 c=2pi(12.5) c=25pi ft
What dimension of a circle is always smaller?
radius
When you make the circle bigger or smaller which number of the standard equation for a circle centered at the origin changes?
Standard equation for a circle centred at the origin is x2 + y2 = r2 where r is the radius of the circle. If you increase the size of the circle then the radius must increase, so r2 will be larger. eg a circle of radius 2 has the equation x2 + y2 = 4, if the radius increases to 3 then the equation becomes x2 + y2 = 9
When you make the circle smaller which number in the standard equation for a circle centered at the origin decreases?
The radius of the circle decreases when you make the circle smaller.
