Answer:
68 in³
Step-by-step explanation:
Cylinder = 3x2x2x3=36
Sphere = 4/3x3x2x2x2=32
36+32=68
Answer:
70√2 units²
Step-by-step explanation:
(see attached for reference notes on parallelograms)
we are given ABCD is a parallelogram where
Short Length, AB = 10 units
Long Length, BC = 14 units
Angle A = 45°
The area of the parallelogram is hence,
= AB x BC sin 45°
= 10 x 14 x sin 45
= 140 sin 45° (recall from special angles, that sin 45° = 1/√2)
= 140/√2 (remove radical from denominator by multiplying by √2/√2)
= (140/√2) x (√2/√2)
=70√2 units²
6 square meters.
Both of these two triangles are exactly the same, so we can find the area of one, the multiply it by 2.
The area of a triangle is calculated using the formula 1/2 * base * height. The base of each triangle is 3 meters according to the diagram, and the height is 2 meters. So, just substitute the values into the equation.
1/2 * 3 * 2
Now, just simplify the expression.
1 1/2 * 2
3
So, the area of each triangle is 3 square meters. Now, just multiply that by 2, so that we have the area of both of the triangles combined.
3 * 2 = 6
This means the total area is 6 square meters.
Answer:The bar model is a pictorial representation of a problem. In a word problem the bar model helps students to visualize the relationship between the numbers given and what are they looking for. For subtraction ( and addition ) you can use Part - Whole bar model. Whole - Part 1 = Part 2.
