Answer:
137.5 in^2
Step-by-step explanation:
So, this is basically a rectangle and two right-sides triangles.
First the rectangle: Formula is A=wl
Replace the Values: A = 14*7 98 in^2
Then we solve for the two right-sides triangles.
A= 1
/2a
h=

/4
b

)
Top trinangle= A = 25.5 in^2 (height 7 in base 7 in)
Bottom Trinagle A = 14 in^2 (height 7 in base 4 in)
Add results:
98+25.5+14 = 137.5 in^2
Answer:
8100g(i.e 8.1kg) is 5.8kg more than 2.3kg
Step-by-step explanation:
Let us convert 8100g to kg.
1000g = 1Kg
8100g = 8100/1000 = 8.1Kg
Now, to know how much is 8100g(i.e 8.1kg) than 2.3kg, we'll find the difference between them as follows
8.1 — 2.3 = 5.8
Therefore, 8100g(i.e 8.1kg) is 5.8kg more than 2.3kg
the height of cylinder B is 4 inches
Answer:
The numbers 1 to 12 must be placed in the circles of the star shown on the right. The sums of the numbers in each row, and the sum of the numbers in the six outer circles of the star, must be equal to 26. Arrange the numbers accordingly.
