Answer:
60.75
Step-by-step explanation:
Use the formula for area of a parallelogram; Base times Height.
Put 4.5 in the formula for base, because it is the base. The formula is now 4.5 times Height.
If the base measures 4.5, and the height is three times that, then multiply 3 by 4.5. This gives you the answer 13.5.
Now put in 13.5 to the equation for height, this is because it is the height that we've now found. The formula is now 4.5 times 13.5.
4.5 times 13.5 is 60.75, so the area of the parallelogram is 60.75 centimeters squared.
.9%. To turn a decimal into a percent, you move the decimal 2 places to the right. So .009 would be .9%
Answer:
m∠C = 66°
Step-by-step explanation:
Given
m∠ A = 33°
m∠ B = 81°
To determine
m∠C = ?
We know that sum of angles of a triangle is 180°.
so using the equation
m∠ A + m∠ B + m∠C = 180°
substituting m∠ A = 33°, and m∠ B = 81° in the equatio
33° + 81°+m∠C= 180°
114° + m∠C = 180°
m∠C = 180° - 114°
m∠C = 66°
Therefore,
Answer:
a. 254.34, b. 56.52
Step-by-step explanation:
a. A = πr^2,
A = 3.14(9^2)
A = 3.14*81
A = 254.34
b. C = πd
C = 18*3.14
C = 56.52
