We already solve for the B or area of the triangular base which was 5.25cm².
There are 2 triangular faces in the prism so 5.25cm² x 2 = 10.50cm²
There are 3 rectangular face in the prism, we need to get the area of each.
area of a rectangle = length x width
rectangle 1: 5 cm x 4 cm = 20 cm²
same dimension with rectangle 2. so, area is 20 cm² also
rectangle 3: 5 cm x 2.8 cm = 14 cm²
let us all add up the area of each surface.
2 triangle = 10.50 cm²
3 rectangles = 20 cm² + 20 cm² + 14 cm² = 54 cm²
10.50 cm² + 54 cm² = 64.50 cm²
160 people x 4 ladle/1 person = 640 ladles full
640 ladles x 1 person/5 ladles = 128 people fed
f(5) is -1
Step-by-step explanation:
- Step 1: Given f(x) = -2x + 9, find f(5)
f(5) = -2 × 5 + 9 = -10 + 9 = -1
Answer:
62.8 square inches
Step-by-step explanation:
we know that
To find out how many square inches of space the rolling pin comes in contact with after one complete roll, determine the lateral area of the rolling pin
The lateral area of a cylinder is given by the formula

we have

substitute
