2x+ 5y = 15<br> 5x+10y = 35<br> O A. (5.-1)<br> O B. (5,1)<br> (<br> O C. (10,-1)<br> O D. (10,1)

Answer:

B.

Step-by-step explanation:

Plug in those x and y values into your equations.

(x, y) = (5, 1)

2x + 5y = 15

2(5) + 5(1) = 15

10 + 5 = 15

5x + 10y = 35

5(5) + 10(1) = 35

25 + 10 = 35

This proves those values are true. So the answer is B.

A cylinder has a diameter of 10 units. Its radius ___ is units. If its height is twice its radius, its height is____ units. Its

denis-greek [22]

Answer:

Volume of cylinder is 785.7 square units.

Step-by-step explanation:

Given the diameter of cylinder 10 units. The height is twice its radius. we have to find its volume.

Diameter, d=10 units

⇒ $\text{Radius,}r=\frac{d}{2}=\frac{10}{2}=5units$

Also given height is twice its radius.

⇒ Height=2(r)=2(5)=10 units

$\text{Volume of cylinder=}\pi r^2h=\frac{22}{7}\times 5^2\times 10=785.4 units^2$

hence, volume of cylinder is 785.7 square units.
