Answer:
<h2>The empty inside the box is 12,870 cubic centimeters, approximately.</h2>
Step-by-step explanation:
Givens
- The diameter of the globe (sphere) is 30 centimeters,
- The box must has dimensions 30x30.
We need to find each volume to subtract them.


The difference betweem the box and the sphere is

Therefore, the empty inside the box is 12,870 cubic centimeters, approximately.
Answer:
39.0953=39cm2
Step-by-step explanation:
Minor arc =70
Angle of arc=70
Then this sector =70/360=7/36 of the circle
Then area = 7/36x3.14x8x8=39cm2 approximatly
Answer:
Given:
Diameter = 38cm
Radius = Diameter /2
Radius = 38 / 2
Step-by-step explanation:
Answer:
34000cm or 340m
Step-by-step explanation:
We have to find total surface area.
dimensions of 1 wooden box =
l = 1m = 100cm
b = 80cm
h = 25cm
∴ In the case of 2 =
l = 100cm
b= 80cm
h = 25 + 25 = 50cm
T.S.A = 2(lb + lh + bh)
= 2(100*80 + 100*50+ 80*50)
= 2(8000+5000+4000)
= 2*17000
= 34000cm
= 340m
