Answer:
2800
Step-by-step explanation:
Just round the 43 to 40 and the 68 to 70. So the problem then converts to 40x70 to get a rough estimate. 40x70=2800
Answer:
7.56 km²
Step-by-step explanation:
Given data:
Width of the fjord, w = 6.3 km
Retreated terminus of the glacier between may 2001 and June 2005, d = 7.5 km
thus, the length lost , y = 7.5 - 6.3 = 1.2 km
now, the area is given as:
A = Length × width
on substituting the values, we get
A = 1.2 × 6.3
or
A = 7.56 km²
Hence, the surface area lost by the glacier in the fjord is 7.56 km²
Answer:
The equation of the sphere in standard form is
Step-by-step explanation:
<u>Step 1</u>:-
The equation of the sphere having center and radius is
Given centered of the sphere is (-6,10,5) and radius r=5
on simplification,we get
simplify , we get
8-2=6
180×6=1080 degrees
sum of interior angle of an octagonal box = 1080 degrees
