Answer:
A=146
Step-by-step explanation:
0.15*146=21.9
28.1+21.9=50
Here you will divide 500 by 6 to get the girl students, and 500 by 5 to get boys.
Answer:
2
Step-by-step explanation:
add 1+1
74.6786 m² is the answer.
Step-by-step explanation:
<u>Step 1</u> :
we know that the diameter (D) of the cookie = 32 ft
Converting dimensions from feet (ft) to meter (m)
1 ft = 0.3048 m
32 ft = 32 × 0.3048
= 9.7536 m
<u>Step 2</u> :
To find the surface area of the cookie we have the formula,
<u> Area (A) = π . r²</u>
Diameter (D) = 32 ft
∴ d = 2r
d/2 = r (radius)
32 ÷ 2 = r
<u> r = 16</u> 16 feet = 4.8768 m
π . r² = 3.14 × (4.8768)² = 3.14 × 23.783
= 74.6786 m²
