Answer:

r = 21

Step-by-step explanation:

(r / 3) = 7

(r / 3)(3) = 7(3)

r = 21

A fraction multiplied by the denominator will equal the numerator.

What is the base area of the cone?

Angelina_Jolie [31]

Answer:

Step-by-step explanation:

In order to find the area of the circle base, we need the radius, and we don't have it. We'll use the volume to find the radius, as follows:

$V=\frac{1}{3}\pi r^2h$ and fill in the givens:

$75=\frac{1}{3}\pi r^2(5)$ and solve that for r;

$r=\sqrt{\frac{3(75)}{5\pi} }$ so

r = 3.784698783 and plug that in for the radius to find the area of the circle base:

$A=\pi r^2$ so

$A=\pi (3.784698783)^2$ gives you that

A = 45 meters squared, exactly. No decimal.

Sin A= ? c/a a/c a/b b/c

S_A_V [24]

Answer:

$\sin A = \frac{a}{b}$

Step-by-step explanation:

Given:

We took here a Right Angle Triangle,Δ ABC at angle B as 90°

Side opposite to angle A = a

Side opposite to angle B = b = Hypotenuse

Side opposite to angle C = c

To Find:

Sin A = ?

Solution:

Property of a Sine rule for a Right Angle Triangle.

$\sin A =\frac{\textrm{side opposite to angle A}}{Hypotenuse}\\\sin A =\frac{a}{b}$

∴ $\sin A = \frac{a}{b}$
