A cylinder has a height of 7cm.

valina [46]2 years ago

We first need to find the radius of the circle, so we need to do 8π/π which gives us a diameter of 8 cm, halving this gives us a radius of 4 cm.

The area of this circle will be:

A = πr^2

A = 4^2

A = 16π cm^2

Now to find the volume we simply multiply the area by the height:

16π × 7 = 112π cm^3 which is our final answer.

The first triangle is an enlargement of the second.
insens350 [35]

Answer:

large triangle:

base = 6.64 cm

hypotenuse = 8.31 cm

small triangle:

base = 4 cm

Step-by-step explanation:

large triangle:

tan 37 = 5/base

0.7536 = 5/base

base = 6.64 cm

using the Pythagorean theorem:

hypotenuse² = 5² + 6.64²

hypotenuse² = 25 = 44.02 = 69.02

hypotenuse = 8.31 cm

small triangle:

using the Pythagorean theorem:

base² = 5² - 3²

base² = 25 - 9 = 16

base = 4 cm
