Answer:
Step-by-step explanation:
I'm guessing you want the volume?
so for a triangle it's 1/2 base * height for the area
1/2 * 8 * 3 = 12
12*20=240 m^3
Answer:
Step-by-step explanation:
- The triangle is isosceles as two sides are radius.
- The central angle and the tangent chord angle refer to same arc.
- Tangent chord angle is half the size of the central angle.
<u>The central angle is:</u>
<u>The other angles in the triangle are equal:</u>
- ∠θ = 1/2(180° - 96°) = 1.2(84°) = 42°
Answer:
Area: 40 cm Perimeter: 30 cm
Step-by-step explanation:
When finding the area of a parallelogram, you use the inside length (in this case, 5cm) and the base (8cm). With perimeter, you use the base and the length (6cm).
8*5=40
8+8+6+6=30
Answer:
N - 7 = 38
-> N = 45
Step-by-step explanation:
Ok, the difference between two numbers, A and B, is written as:
A - B
Then "The difference of a number and 7..."
is:
N - 7
Where N is the number.
And we know that:
N - 7 = 38
Then with this, we can find the value of N. The way of isolating N, is adding 7 in both sides of the equality, then we get:
N = 38 + 7 = 45
