Answer 1

Step-by-step explanation:

The area, originally inhabited by the Tongva (or Gabrielino) Indians (its name derives from the Indian word kukamonga, meaning “sandy place”), was explored in 1769 by a Spanish expedition led by Gaspar de Portolá. ...

Answer 2

Surface area of cylinder is 251.42 sq.cm

Given that

Radius of cylinder is 5cm

Height is 3cm

To find

Surface area of cylinder

Solution

As we know that

Let

r as radius of cylinder

h as height of cylinder

s as surface area of cylinder

$surface \: area \: of \: cylinder = 2\pi \times r \times h + 2 \times \pi \times {r}^{2}$

$s = 2 \times \pi \times 5 \times 3 + 2 \times \pi \times {5}^{2}$

by multiplication

$s = 30\pi + 50\pi$

$s = (30 + 50)\pi$

$\pi = \frac{22}{7}$

now

$s = 80 \times \frac{22}{7}$

by multiplication we get

$s = 251.42 {cm}^{2}$

Hence surface area of cylinder is 251.42 cm sq.
