the lateral area of a cylinder is 325 pi in2 the radius is 13 in find the following Volume. surface area

1 answer:

5 0

Volume: 2112.5π
Surface Area: 663π

First, let's find the height of the cylinder. Using the formula for lateral surface area, 2*π*r*h:

2*π*13*h = 325π
(divide π by both sides)
26h = 325
h = 12.5 in.

Next, let's solve the surface area of the cylinder using the formula π*r²*h.

π * 13² * 12.5 = π * 169 * 12.5 = 2112.5π.

Next, let's solve the surface area using the formula 2πrh + 2πr².

(2 * π * 13 * 12.5) + (2 * π * 13²) = 325π + 338π = 663π.

Law of cosine find m<B a=11 b=12 c=17

Andrei [34K]

Cos (B) = (a^2 + c^2 -b^2) / (2 * a * c)
cos (B) = (11^2 +17^2 -12^2) / (2 * 11 * 17)
cos (B) = (121 + 289 -144) / (374)
cos (B) = 266 / 374
cos (B) = 0.7112299465
Angle B = 44.665 degrees

From the earth, the moon subtends an angle of approximately 0.5°. If the distance to the moon is approximately 240,000 miles, fi

konstantin123 [22]

Answer:

2100 miles.

Step-by-step explanation:

Given:

Diameter to the moon = 240000 miles

∅ = 0.5 °

The subtended angle by an arc is given as:

S = r∅

Where

r = radius of the circle

Therefore,

D = 240,000 x (0.5 x π rads)/180

= 2094 miles

= 2100 miles.

The total price of an article is $7.02, including tax. If the tax rate is 8%, what is the retail price of the article?

masya89 [10]

Lets price of article = x
Tax is 8% of article = 0.08x

x+0.08x=7.02
1.08x=7.02
x=7.02/1.08
x=6.5
The retail price is $6.50.
