PLEASE HELP!

Wittaler [7]

Answer:

See below

Step-by-step explanation:

Use the formulae directly

For a cone, with base radius = r and height = h, here are the related formula

$\textrm{Slant height l} = \sqrt{r^2 + h^2}$ (1)

$\textrm{Lateral surface area} = \pi r l$

$\textrm {Base area} = \pi r^2$

$\textrm { Total Surface Area SA} = \textrm{Base Area + Lateral Area} = \pi r^2 + \pi rl = \pi r(r + l)$ (2)

$\textrm{Volume V = } (1/3) \pi r^2h$ (3)

Therefore directly plugging in the numbers in the above equations:

Note:

l = slant height in cm
SA = total surface area in sqcm
V = Volume in cubic cm

Figure(a)

r = 4, h = 8

$\textrm{l} = \sqrt{4^2 + 8^2} =\sqrt{80} = 8.944 \\\textrm{SA} = 4\pi(4 + 8.944) = 4\pi(12.944) = 162.66\\\textrm{V} = (1/3)\pi(4^2)(8) = 134.04$

Figure(b)

r = 7, h =15

$\textrm{l} = \sqrt{7^2 + 15^2} =\sqrt{274} = 16.55$

$\textrm{SA} = 7\pi(7 + 16.55) = 517.89$

Figure (c)

r = 5, l = 8

$h = \sqrt{l^2 - r^2} = \sqrt{8^2 - 5^2} = \sqrt{39} = 6.245\\SA = \textrm{SA} = 5\pi(5 + 8) = 204.2\\V = (1/3)\pi(5^2)(6.245) = 163.5$

A motorboat travels 60 km in 4 hours with the current and 35 km in 3.5 hours against the current. Find the speed of the boat in

IceJOKER [234]

Step-by-step explanation:

Distance = rate × time

If b is the speed of the boat in still water, and c is the speed of the current, then:

60 = (b + c) × 4

35 = (b − c) × 3.5

Simplifying:

15 = b + c

10 = b − c

Add the equations together:

25 = 2b

b = 12.5

Plug into either equation to find c:

c = 2.5

The speed of the boat is 12.5 km/h, and the speed of the current is 2.5 km/h.

Ada buys 3 pounds 8 ounces of ham and 4 pounds 2 ounces of cheese for a party. How much ham and did she buy ?

Lesechka [4]

C) 7 pounds 10 ounces 7 5/8

3 ponds + 4 pounds = 7 pounds
8 ounces + 2 ounces = 10 ounces
16 ounces in a pound
7 pounds 10/16 ounces
reduce '10/16' to '5/8'
