Answer:
28 units²
Step-by-step explanation:
→ Work out the size of the triangle if it was a full rectangle
Height = 4 and Base = 2
→ Work out area of triangle
0.5 × Height × Base ⇒ 0.5 × 4 × 2 ⇒ 2 × 2 ⇒ 4
→ Minus the area of the triangle from the "imaginary full' rectangle
Area of rectangle = Length × Width ⇒ 8 × 4 ⇒ 32
32 - 4 = 28
The formula for Circumference is C= πd (with C being Circumference and D being diameter). You would substitute the information into the equation, to find the diameter. After, finding the diameter divide it by 2 to find the radius. When you find the value of the radius, substitute it into the equation (v=4/3πr^3). Volume equals 4 divided by 3, times pi, times the radius cubes (to the power of 3).
