Volume of a cone = (1/3) x Area of the base (B) x height(h)
V = (1/3)·420·180
= 25200 mm³
Answer:
2.255
Step-by-step explanation:
2.05 + 10% = 2.255
Answer:
the formula for the area of a triangle is a= b*h/2
Step-by-step explanation:
area= base* height divided by two.
if a triangles base was 5 height was 4 the area would be 10units
5*4=20
20/2=10
I used a random example as the specific example was not listed in the question.
Answer:
95.9 cm^2
Step-by-step explanation:
this figure is composed of two semicircles. the area of each semicircle would be determined and then added together.
area of a semicircle = 1/2 nr^2
r = radius
n = 22/7
bigger semicircle
1/2 x (22/7) x (6^2) = 56.57cm^2
smaller circle = 1/2 x (22/7) x (5^2) =39.29cm^2
Sum of the areas = 56.6 + 39.3 = 95.9 cm^2
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
Answer:
Step-by-step explanation:
108 = 2*2*3*3*3=2² * 3³
120 = 2*2*2*3*5=2³*3*5
LCM = 2³*3³*5 = 8*27*5= 1080
