Answer:
Step-by-step explanation:
The total surface area of a cone is given by:
Surface area = 
where r is the radius of the cone, h is the height of the cone, l is the length of the cone = 
Given that h = 136 mm, r = 60 mm /2 = 30 mm, l = 140 mm. Also the top of the cone is not included in the surface area, hence the surface area becomes:
Answer:
Step-by-step explanation:
Equation of line
y = mx + c
m = slope and c is the intercept on y-axis
Answer:
2
Step-by-step explanation:
Find the greatest common factor of 8, 18, and 70.
Since we are looking for the Greatest Common Factor of the numbers given, we begin by factoring the numbers. It is usually easiest to start with the smallest number. Also, if there is a number that has obvious factors. In our case, satisfies both of these:
8=2⋅2⋅2 In fact,
8 only has one unique factor! If there is to be a common factor (other than
1 ) it must be
2. We now need to check that both
18 and 70 have 2 as a factor:
18=2⋅9
70=2⋅35 Therefore, 2 is the GCF of 8, 18 and 70.
Answer:
A
Step-by-step explanation:
Observe the coordinates of C, it's (5,2). Now observe C' which is (2, - 5). Hence the rule is (x, y) -> (y, - x)
The answer is the ratio of A's to the number of classes is 7 to 4. That's false. For the statement to be true the ratio should have been 4 to 7.
