Answer:
216 degrees is the answer.
Step-by-step explanation:
The vertical height of the cone = 8 cm
The radius of the cone = 6 cm
The perimeter or circumference of the base of the cone is given by:
P = 
= 
Now the slanted height is calculated using Pythagoras theorem:
H = 
= 
= 10
Let 'θ' is the sector angle that we have to find.
Arc length of the sector is equal to the perimeter.
Arc length = 
θ
θ
θ=
(radian)
we know that 1 pi radian = 180 degrees.
So, 1.2 pi radian = 
degrees
The van will need 25 gallons of gas for it to travel 550 miles. This is calculated by dividing 10 gallons to 220 miles to get the miles per gallons, which in this case is 22 miles per gallon. Then we have to divide 550 miles by 22 miles per gallon to get the total gas consumption, which is 25 gallons.
Answer:
(i) 32 cubic meters, (ii) 800
Step-by-step explanation:
(i) 1 x 4 x 0.5 = 2 m3, x 16 = 32
(ii) 1000 litre per m3 = 32,000 litres required divided by 40 = 800 bags.
When simplifying an expression, you collect and simplify all the like terms. Since 8x and -12 aren’t like terms, you can’t substract 8-12
Answer : comedy = 48 dvd, action = 64 dvd, horror = 40 dvd
Explanation:
Find comedy dvd:
152 x 6/(6 + 8 + 5) = 152 x 6/19 = 48
Find action:
152 x 8/19 = 64
Find horror
152 - (64 + 48) = 152 - 112 = 40
