Hello! answer: 105
Step-by-step explanation:
You can find the area separately then add it up so... 10 × 6 = 60 10 × 9 = 90 90 ÷ 2 = 45
60 + 45 = 105 therefore the area is 105
Answer:
105 square meters
Step-by-step explanation:
Area= a + b/2 • h
Area= 15 + 6/2 • 10
Area= 21/2 • 10
Area= 10.5 • 10
Area= 105

4.5 * 4.5 * 3.14 which will equal 63.585 inches squared
Hope this helps
Answer:
D. 4.5
The Area is 63.585
Step-by-step explanation:
So the diameter is twice the size of the "r" or radius so divide 9 by 2
which is 4.5
The formula for a circle is πr^2
4.5 times itself is 20.25
times pi or 3.14 is 63.585

An altitude is drawn from the vertex of an isosceles triangle, forming a right angle and two congruent triangles. As a result, the altitude cuts the base into two equal segments. The length of the altitude is 30 inches, and the length of the base is 10 inches. Find the triangle’s perimeter. Round to the nearest tenth of an inch.
Answers
Step-by-step explanation:
From the given question, applying the Pythagoras theorem to one of the congruent triangles formed, we have;
= +
= +
=841 + 81
= 922
hyp =
= 30.3645
The perimeter of the triangle can be determined as;
perimeter = + +
= 30.3645 + 18 + 30.3645
= 78.729
The perimeter of the triangle = 78.7 inches
The perimeter of the triangle is 70.82 inches.
Given as :
The length of the altitude is 30 inches, and
The length of the base is 10 inches
What is right triangle?Right triangle is defined as a triangle which one angle is a right angle or two sides are perpendicular.
Let, perpendicular = 30 and base = 5
According to Pythagoras theorem,
A right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
perpendicular² + base² = hypotenuse²
Substitute the values,
30² + 5² = hypotenuse²
900 + 25 = hypotenuse² or
hypotenuse² = 925
hypotenuse = √925
hypotenuse = 30.41
The perimeter of the triangle can be determined as:
Perimeter of the triangle = l₁ + l₂ + l₃
Perimeter of the triangle = 30.41+ 10 + 30.41
Perimeter of the triangle = 70.82
Hence, the perimeter of the triangle is 70.82 inches.

Avi's pet hamster Chubby loves to run in his hamster wheel. During one "race", Avi counts 1000 rotations of the wheel. She wants to know how far Chubby ran, so she measures the diameter of the wheel and finds that it is 20 cm. How far did Chubby run
Answers
Answer:
i think its 200 m
Step-by-step explanation:
because 20 times 1000 rotations is 20000 cm so when u convert it to meter it is 200 meter if it is km it is 0.2 km
The diameter of hamster wheel = 20 cm
Now the circumference of hamster wheel is given by :-
where d ⇒ the diameter of the hamster wheel.
During one race, the number of rotations of the wheel = 100
Therefore, the distance run by chubby is given by :-
Distance ran by chubby is equal to the number of rotations of the wheel times Circumference of the wheel.
framing in equation form we get;
D⇒ Distance ran by Chubby.
