<u>Geometry</u>

Area of a Circle Formula: A = πr²

  • r is radius

Step-by-step explanation:

<u>Step 1: Define</u>

Radius <em>r</em> = 6

<u>Step 2: Solve</u>

  1. Substitute in variable <em>r</em> [Area of a Circle Formula]:                                        A = π(6)²
  2. [Area] Evaluate exponents:                                                                              A = 36π

The diameter of a sphere is 10 in. What is the sphere's volume? Round to the nearest tenth, if necessary. A) 104.7 in3 B) 209.4
denis23 [38]
To find the volume of a sphere, you will use the formula for finding volume of a sphere. You will use the diameter to find the radius.  r = d/2, so the radius is 5 in

V = 4/3 x pi x r^3
      4/3 x 3.14 x 5^3
V = 523.6 cubic inches

The volume of this sphere is approximately 523.6 cubic inches.

Please help! 10 points and brainlyist!!
yarga [219]

Answer:

1.80 in^3

1.0 fluid ounces^3

Step-by-step explanation:

volume of a cone = 1/3 πr²h

π = 3.14

r = 2.2 / 2 = 1.1

h = the value of h can be determined using Pythagoras theorem

The Pythagoras theorem : a² + b² = c²

where a = length

b = base

c =  hypotenuse

1.8² = 1.1² + b²

3.24 = 1.21 + b²

3.24 - 1.21 = b²

2.03

b = √2.03 = 1.42

Volume = 1/3 x 3.14 x 1.21 x 1.42 = 1.80 in^3

1.80 x 0.554 = 1.0 fluid ounces^3

The altitude of a triangle is increasing at a rate of 1 cm/min while the area of the triangle is increasing at a rate of 2 cm2/m
Mnenie [13.5K]

Answer:

The base is reducing at a rate of 3.4cm per min.

Step-by-step explanation:

Let The Height of the Triangle, h

Area of the triangle = A

Area of a Triangle, A= \frac{1}{2}bh

When A=190 cm^2, h=10cm

190= \frac{1}{2}*b*10\\b=38cm

\frac{dA}{dt}=\frac{1}{2}h\frac{db}{dt}+ \frac{1}{2}b\frac{dh}{dt}\\\frac{dh}{dt}=1 cm/min, \frac{dA}{dt}=2cm^2/min,

2=\frac{1}{2}*10*\frac{db}{dt}+ \frac{1}{2}*38*1\\2=5\frac{db}{dt}+19\\2-19=5\frac{db}{dt}\\-17=5\frac{db}{dt}\\\frac{db}{dt}=-\frac{17}{5} =-3.4 cm/min

The base is reducing at a rate of 3.4cm per min.
