Answer:
Volume of cone = 418.67 cm³ (Approx.)
Step-by-step explanation:
Given:
Radius of cone = 5 cm
Height of cone = 16 cm
Find:
Volume of cone
Computation:
Volume of cone = [1/3][π][r²][h]
Volume of cone = [1/3][3.14][5²][16]
Volume of cone = [1/3][3.14][25][16]
Volume of cone = [1/3][3.14][400]
Volume of cone = [1/3][1,256]
Volume of cone = 418.67 cm³ (Approx.)

Have a great day!
Hi , 3/4 times 28 equals to 84/4
28 is equivalent to 28/1
we just multiply straight across
28 x 3 equals to 84
4 x 1 equals to 4

Be sure to include the "=" sign: <span>f(x) = 2^x -7
To find the x-intercepts, set f(x) = 0 and solve for x: 2^x - 7 = 0,
or
2^x = 7
Take the common log of both sides: x log 2 = log 7
log 7
Solve for x: x = --------- = 2.81 (approx)
log 2

So for every 6 people with a car, there are another 5 that own an SUV, or expressed the other way around, for every 5 SUVs, there's one extra car. If there are 200 extra cars, that means there are 5 × 200 SUVs = 1000 SUVs, and 1200 cars.
Now let's just quickly test if the math is correct, and if the ratio of cars to SUVs is still 6:5:
1200 : 1000 << get rid of the 00
12 : 10 << divide by two
6:5
Yep, math is correct.
Answer: There are 1200 people who own cars, and 1000 people who own SUVs.
