Answer:

Kobby is 1 and Nana is 6

Step-by-step explanation:

lets mark Kobby's present age x, than Nana's present age would be x+5.

four years later Kobby's age would be x+4, and Nana's x+5+4, or 2(x+4).

x+5+4=2x+8

x-2x=8-5-4

-x=-1

x=1

The spherical bottle has a conical shaped lid with a diameter of 5cm and a height of 4.5cm. Given this information, calculate th

Harlamova29_29 [7]

Answer: Volume of lid = 29.44 cubic cm and surface area = 40.41 cubic cm.

Step-by-step explanation:

Given: For lid of the spherical shaped bottle,

Diameter = 5 cm

Height = 4.5 cm

Radius = Half of diameter = 2.5 cm

Volume of cone = $\dfrac13\pi r^2 h$

Volume of lid $=\dfrac13(3.14)(2.5)^2(4.5)=29.4375\approx29.44\text{ cm}^3$

Surface area of cone = $\pi r\sqrt{h^2+r^2}$ [as lide has no base we don't include area of base.]

Surface area of lid = $(3.14)(2.5)\sqrt{(2.5)^2+(4.5)^2}= 7.85\sqrt{26.5}\approx40.41\text{ cm}^3$

Hence, volume of lid = 29.44 cubic cm and surface area = 40.41 cubic cm.
