a circular fountain has a radius of 9.4 feet. find its diameter and circumference to the nearest tenth.

pickupchik [31]

Radius = r

Diameter : D = r*2

Circumference : C = 2πr

π = 3.14 rounded

9.4*2 =18.8

2(3.14)9.4

6.28*9.4= 59.03200

Diameter = 18.8

Circumference = 59.03200

If a = 0.3 and b =0.5, what is the value of a+b?

Alborosie

Answer=

Step-by-step explanation

because of the dot/line at the top of the number it means it is a continuous same number

for example, 0.3 with a dot/line on top means it is 0.333333...

so 0.55...+0.33...=0.88...

and as it is a decimal that is in the range of 1-100 its like a percentage so it is 88/100

Solve for x if DEFG is a parallelogram

NeTakaya

Opposite sides of a parallelogram are congruent, so you know that 2x + 2 = 3x - 3. start by adding 3 to both sides to get 2x + 5 = 3x. then subtract 2x from both sides to get 5 = x.

Both circle Q and circle R have a central angle measuring 60°. The area of circle Q's sector is 9π m2, and the area of circle R'

GuDViN [60]

Answer:

The ratio of the radius of circle Q to the radius of circle R is $\frac{3}{4}$

Step-by-step explanation:

step 1

Find the scale factor

we know that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

In this problem

Let

z-----> the scale factor

x-----> the area of circle Q's sector

y-----> the area of circle R's sector

$z^{2}=\frac{x}{y}$

substitute

$z^{2}=\frac{9\pi}{16\pi}$

$z^{2}=\frac{9}{16}$

square root both sides

$z=\frac{3}{4}$ ------> scale factor

step 2

Find the the ratio of the radius of circle Q to the radius of circle R

we know that

If two figures are similar, then the ratio of its corresponding sides is equal to the scale factor

In this problem

The ratio of its corresponding radius is equal to the scale factor

Let

z------> the scale factor

x-----> the radius of circle Q

y-----> the radius of circle R

$z=\frac{x}{y}$

therefore

$\frac{x}{y}=\frac{3}{4}$
