Find the value of x. help with geometry pls

Ivan

Answer:

Find the value of x:-

To find Y, use Pythagorean theorem:- $c^{2} =a^{2} +b^{2}$

$(2.1)^{2} =y^{2} +(1.4)^{2}$

$2.1^{2}=4.41$

$1.4^{2} =1.96$

$4.41=y^{2} +1.96$

subtract 1.96 from both sides

$2.45=y^{2}$

$y=1.5652$

Now, to find x:-

$x=y+y$

$= 1.5632+1.5652$

$x=3.1 \: ft$

The diameter of this beach ball is 12 inches.

Wittaler [7]

Answer:

288π or 904.78

Step-by-step explanation:

We know that the diameter of this beach ball is 12 inches and we want to determine how much air it can hold using the formula for the volume of a sphere which is $\frac{4}{3}$ × π × r³ where 'r' is the radius. In the question we are given the diameter not the radius but we can half the diameter to find the radius so 12 ÷ 2 = 6. The radius of the beach ball is 6 inches so let's work out how much air it can hold.

Volume = $\frac{4}{3}$ × π × r³

→ Let's substitute in the values

Volume = $\frac{4}{3}$ × π × 6³

→ Simplify

Volume = $\frac{4}{3}$ × π × 216

→ Simplify further

Volume = 288π or 904.78

A length is measured at 21 cm correct to two significant figures, what is the lower bound of the length and upper bound?

Andreyy89

Answer:

20.5 and 21.5

Step-by-step explanation:

It says 2 significant figures so the least it can possibly be is 0.5 less and the most it can be is 0.5 more as if it was, lets say 20.4 it would round down to 20 not 21.
