Answer:
First lets find the area of the bottom circle:
7.2 is your radius so:
7.2^2 = 51.84 the reason why you square your radius is because thats apart of the formula when finding the are of a circle.
lets continue:
51.84 x 3.14(pi) = 162.7776
Now we need to find the area of the round surface but first we need to find the circumference of one circle and multiply it by the height.
2 x 3.14 x 7.2 = 45.216
Now lets multiply it by the height:
45.216 x 17 = 768.672
Now lets add both areas:
768.672 + 162.7776 = 931.4496 dont forget to round to the nearest hundredths place! 931.4496 rounded up = 931.45 square meters is your answer.
Its b and a hope this helps
Answer:
Step-by-step explanation:
Given
x² + x
To complete the square
add ( half the coefficient of the x- term )² to x² + x
x² + 2(
)x + ( )² = x² + x +
= (x + )² ← perfect square
