Juli2301 [7.4K]

For i=1 ===> Sum=4

for i=2===> Sum=2

for I=3===> Sum=1

Hence the answer is 7

Or you could have use the Sum formula of a GP:

Sum = a(1-r)^n/(1-r), with a=1, r=1/2 & n=3

A city has cone shaped buildings for storing salt and sand for icy roads. Each building has a radius of 50 feet and a height of

aalyn [17]

Answer:

Radius=50 ft
π=3.14
Height=30 ft
Volume=?

We know that,

$\star \: \: \purple{Volume_{(cone)} =\pi {r}^{2} \frac{h}{3} }$

$\star \: \: \purple{Volume_{(cone)} =3.14 \times {(50)}^{2} \times \: \cancel\frac{30}{3} \: }$

$\star \: \: \purple{Volume_{(cone)} = 3.14 \times (50 \times 50) \times 10}$

$\star \: \: \purple{Volume_{(cone)} =3.14 \times 2500 \times 10 }$

$\star \: \: \purple{Volume_{(cone)} =78500 }$

Thus,the third option is correct.
