Answer:

x = 13

Step-by-step explanation:

Since the polygons are similar, their side lengths will be proportionate.

So, The ratio (x - 3)/2.5 will be proportionate to 16/4 (4).

That said, we can get that (x - 3)/2.5 = 4

Multiply: x - 3 = 10

Add: x = 13

olga55 [171]

Answer:

Volume of the sphere up to two decimal places= $4.19$ cubic yards

Surface area of the sphere up to two decimal places $=12.56$ square yards

Step-by-step explanation:

Given:

The radius of the sphere= 1 yard

Volume of a Sphere:

$\frac{4}{3}* \pi *r^3$ : $\pi =\frac{22}{7} =3.14$

$=\frac{4}{3}*3.14*1*1*1$

$=4.187$ cubic yards

Volume of the sphere up to two decimal places= $4.19$ cubic yards

Surface area of the sphere= $4*\pi* r^2$

$=4*3.14*1*1$

Surface area of the sphere up to two decimal places $=12.56$ square yards
