A)
Obw= 2*3,14*2 =12,56cm
Obw = 6,28*4 = 25,12m
Obw = 6,28*0,3 = 1,884cm
Obw = 6,28*10 = 62,8km

b)
Obw = 6,28*1 = 6,28cm
Obw = 6,28 * 1,5 = 9,42m
Obw = 6,28 *0,2 = 1,256cm
Obw = 6,28 *100 = 628m

c)
6,28*r = 10m
r≈1,59m

6,28*r = 1m
r≈0,159

6,28*r = 628mm
r=100mm

6,28*r = 3,5cm
r≈ 0,557cm

World oil reserves amount to about 10,000 EJ, and humankind uses energy at the rate of roughly 18 TW. If all our energy came fro

Volgvan

Answer:

t=17.61 years.

Explanation:

Given that

Reserve of energy = 10,000 EJ

Energy used by human = 18 TW

We know that

$1\ E= 10^{18}$

$1\ T= 10^{12}$

$Reserve\ of\ energy = 10,000 \times10^{18} J$

$Reserve\ of\ energy = 10^{22} J$

$Energy\ used\ by\ human = 18 \times10^{12}\ W$

Lets t time after energy will be exhaust

$18 \times10^{12}\times t=10^{22}$

$t=\dfrac{10^{22}}{18 \times10^{12}}\ s$

$t=5.55\times 10^8 \ s$

We know that

1 year = 365 days

1 year = 365 x 24 hr

1 year = 365 x 24 x 3600 s

$1year =3.15\times 10^7\ s$

$t=\dfrac{5.55\times 10^8 }{3.15\times 10^7}$

t=17.61 years.
