C = 2π×r
C =2π×7
C = 14π cm

7) C = 2π r

18π = 2π r

r = 9
diameter = 2r
diameter = 18 inches

Find the circumference of the circle and show work

expeople1 [14]

Answer:

$\huge\underline{\red{A}\blue{n}\pink{s}\purple{w}\orange{e}\green{r} -}$

Circumference of a circle is given by

$C = 2\pi \: r$

Given - Diameter of circle = 10 yards

$radius = \frac{diameter}{2} = \frac{10}{2} \\ \\ \implies \: 5 \: yards$

now ,

substituting the value of r in the formula of circumference ~

$C = 2 \times \frac{22}{7} \times 5 \\ \\ \implies \: C = \frac{220}{7} \\ \\ \implies \: C = 31.43 \: yards \: (approx.)$

hope helpful :D

Answer:

275 ft³

Step-by-step explanation:

Given the ratio of radii of 2 similar figures = a : b , then

ratio of volumes = a³ : b³

Here the ratio of radii = 5 : 2 , so

ratio of volumes = 5³ : 2³ = 125 : 8

Calculate the volume (V) of A using proportion

$\frac{125}{V}$ = $\frac{8}{88}$ = $\frac{1}{11}$ ( cross- multiply )

V = 275 ft³

That is the volume of figure A = 275 ft³

An equation is shown 27+18 (3+2) What factor is missing from the equation?

yarga [219]

$\mathbb{\pink{\huge{Hello\:Mate!!}}}$

$Answer$

$Equal sign is missing out there.$

$Step-by-step explanation.$

If it is an equation, there must be equal sign present. It means, we are equating something. If there is equal sign, then it can't be an equation.

$Thanks....!$
